Used electric cars are the steal of the century. You can find 2–3 year old Nissan Leaf cars going for under $10,000 with only 20 to 40 thousand miles. I was looking to buy a few Fiat 500e coming off lease, so only three years old, to ship to Europe and my criteria were miles below 20,000 at under $7000.
Normally when a car’s resale value is so low it's because of terrible reliability. To the contrary with electric cars. They are proving to be at least ten times more reliable than ICE cars.
Andre Lavoie:
I should post a link to data on reliability. I read about the E car being 10–100 times more reliable. There are no moving parts, save for an electric motor shaft. Everything else is solid state. ICE cars have thousands of moving parts that do wear out. You know it!
Personal experience: Audi A4, $20,000 in maintenance and repairs over ten years. Probably I was getting ripped off and should have found a better deal, but I knew my mechanic did good work.
Now, Nissan Leaf, almost six years and I have had no maintenance that you don't already do on an ICE car: wiper blades, tires, cabin air filter and brake fluid oil. I was getting concerned I should get it checked out so went to the dealer. I just leaned on my window sill and basically said there is nothing to do.

Question: “Why is a timing belt preferred to a chain?”
Answer (by Michael Kay):
OK. I would have to initially propose a counter question: Preferred by whom?
A timing belt would NEVER be preferred by a gear head or an enthusiast. They are, however, extremely common on automobile engines. Why?
This is a typical engine timing belt (pic 1)
Compare this to a timing chain (pic 2)
Or a timing gear system (pic 3)
The timing belt has TWO advantages over the other systems. 1) IT IS CHEAPER…A LOT CHEAPER, TO MANUFACTURE. 2) In operation it runs more quietly than either a chain drive system or especially a gear drive system. It is, after all, nothing more than a glorified toothed V-belt, not an assembled or machined part. Timing belts are really cheap to make.
Their cheapness is, of course, the primary reason why manufacturers choose to design timing belt systems into engines, especially those engines used in cars sold at the bottom low-priced end of the market. In that segment, price sells, and the usual customer in that market does not know, or care, what sort of an engine is located under the hood, and would not have any idea what you were talking about when you mentioned either timing belts or timing chains.
Moreover, an unpaid for advantage of timing belts, that they run quietly, can enhance the perception of, and salability of, a timing belt equipped car,
especially to the customer who knows nothing about engines. Controlling NVH (Noise, Harshness, and Vibration) takes engineering skill and is expensive. Thus, we have come to associate quiet engines with high quality. If a manufacturer is able to obtain that sound of quality with a cheap part, he is able to trick the uninformed customer into thinking that the car is built to higher standards than is in fact the case. For the manufacturer, what is not to like?
But, as I said, no gear head or enthusiast likes timing belts? Why?
Let me give you a bunch of reasons: Timing belts break. They are rubber and fiber parts that deteriorate, especially in the presence of oil and fuel and heat. And guess what you find in an engine compartment…oil and fuel and heat. Moreover, when they do break, if you have an interference engine, something like this happens.
The engine can be damaged so catastrophically that repair is not financially reasonable. You will have to buy a new engine.
Timing belts are cheap to make but expensive to own. Because all timing belts will eventually fail, and that failure can lead to catastrophic engine damage, they have to be periodically replaced. The recommended replacement schedule for timing belts is generally 60k to 100K miles and five to seven years. And the service needed to replace a timing belt is very expensive . That is not because the belt is expensive. It is a cheap part. However, the number of components the mechanic has to remove just to get at the timing belt requires a lot of expensive labor hours.
These are just SOME of the parts surrounding the timing belt. Many of them are hard to access because of the position of the engine in the car.
But timing chains and gears break too, right?
In all my years of of building high performance engines I HAVE NOT EXPERIENCED ONE TIMING CHAIN OR TIMING GEAR FAILURE. Although it is possible, if an owner has really abused a car and has driven it way beyond its expected lifespan, timing chain and gear failures are very uncommon. Every one of which I am aware was caused, not by a failure of the timing chain, but rather because of another cheap part installed on a low end engine by a manufacturer.
Some manufactures chose to use fiber timing gears such as these.
This one is from a Ford T, but fiber timing gears were installed through the 1970’s and probably later. They were chosen because they ran more quietly than machined metal gears. But they did deteriorate. And when they did they would chew off their own teeth.
The only other timing chain failures of which I am aware were caused by the use of plastic chain guides in an engine that when worn could cause problems. The design was changed and all of those engines had those guides replaced with machined metal parts.
Chains can stretch, and if the chain guides or tensioners are absent or worn there can be problems. But an advantage chains have over belts is that you will be forewarned of a possible chain failure before damage occurs. Belts can fail abruptly and without warning, long before the engine is anywhere near the end of its service life. And that belt failure can cause catastrophic damage. Every mechanic recognizes the distinctive sound made by a loose chain. If you have your car properly serviced, he will recognize that sound and warn you so that you can have the car serviced before damage occurs.
The best engines employ gear drives or gear and chain drives for the camshafts.
As for the greater noise made by chain and gear drives? For a gear head the sound made by the gear drives of a Ferrari is heavenly! - #58 [ckwan2014], 17-11-30 23:238年前,小弟從SFO登陸北美。
學車係用師傅架90年代尾Toyota Corolla
第一架正式揸嘅車係老竇架1993' Toyota Camry I4,
第一架買嘅係1995' Mazda 626(受香港汽車文化熏陶),殊不知架車有事,hydraulic lifter好快打柴,啲聲成架柴油車咁。
之後再入另一架1998' Accord Coupe。
5年前,架Camry幸運地賣咗俾老竇個朋友,未幾就柴咗波箱收工。之後架626催化太老過唔到年檢,順手退埋休收返$1000入袋($1300買返黎,小小一個教訓)。
半年後,係做工嘅修車行幫老竇買咗架2007' Toyota Matrix(Corolla底盤,Torsion Beam尾擔)。
3年前,老竇仙遊,架Matrix轉咗我揸,Accord Coupe就賣咗俾當時揸貨柜車嘅同事。

自由騎士, 不受束縛
Motorcyclists, by rule of thumb, understand the importance of safety measures and gear. Still, some of them prefer to ride without a helmet and prefer to feel the ultimate freedom that riding a motorbike allegedly offers.
New Yorker Phil Contos (55) was riding bare headed in a protest ride protesting helmet laws. For an unknown reason, Contos slammed his brakes, fishtailed out of control, flew off his bike head first and was killed on the spot.
堅持信念
His elder brother later said that had his brother survived, he would have probably continued protesting against helmet laws, and the circumstances of his death were how Contos wanted to go.
事件係咪反教材?
We think that he proved that helmets and protective gear are essential.

該獎項以著名演化論學者查爾斯·達爾文命名,是因為獎項的得主均失去了繁殖的能力
或者是榮譽得主已去世
「讓自己愚蠢的基因不再自由地傳播出去」,對人類的演化做出了貢獻。亦有人認為,
達爾文獎是用來記錄「那些在演化過程中走得最慢的人們」
"In the spirit of Charles Darwin, the Darwin Awards commemorate individuals who protect our gene pool by making the ultimate sacrifice of their own lives. Darwin Award winners eliminate themselves in an extraordinarily idiotic manner, thereby improving our species' chances of long-term survival

(1) 捨命救車
We all love our cars. Some more than others, but we all love our cars.
So did an Italian man named Gerhard.
打尖偷先駛過鐵路, 點知愛車死火.
While waiting in line with other cars for a train to pass, he lost his patience and decided to cut the queue and try and cross the tracks. The safety bars came down just as his Porsche Cayenne SUV was dead on the tracks.
及時跳出, 本來冇事,
Gerhard jumped out of the car and ran towards the train, hoping in vain that the conductor would stop the train and save his beloved SUV.
竟然走向火車, 意圖呼停
Gerhard was hit by the train and was knocked 30 meters away dying instantly.
(2) 高速自拍
Giovana Alves Dias de Souza, a young Brazilian woman, had a serious need for speed. Like many other millennials, she also had a fetish for documenting herself, more often than not, at the wrong time and at the wrong place.
So one night, while speeding at 180 K”m/h she was able to take a selfie with the speedometer and post it on her Facebook page. Figuring that only a fool will do the same experiment twice and expect different results, she did the same thing again. Police found her car wrapped around a support pole, her mobile showing a photo of her and her speedometer clocking 170 k”m/h.

Why are Mini Coopers so expensive?
Answer by Leon Alvarado
The new Mini is basically a BMW. The brand was purchased by BMW back in 1994 when it acquired the Rover Group. In 2000 they re-designed the vehicle that has been famous since 1959. The first models however had a Tritec powerplant which was basically a Chrysler straight-4 engine. In 2006 the second generation came out with a much improved chassis and a Prince engine which is a compact engine family built by PSA Peugeot Citroen.
In 2014 the Mini finally got a BMW engine (B48). The car had extensive use of aluminum components to reduce weight and several improvements over its predecessor.
The Mini is assembled in the UK and in the Netherlands (depending of which model). It runs on BMW’s UKL platform that’s shared with BMW’s 2 series and the BMW X1.
So why do they seem so expensive?
You are basically buying a BMW engineered, European built, imported car.
When looking at it from that point of view, they aren’t really that over-priced. Plus, they are a lot of fun to drive. Anyone who owns one can attest
to that
