Not true at all. I drove mine for 2 years and never had a problem. Never and that was in 86
Drove it for two years and never had a problem. That's what you think reliability is?
When I was younger I had a Toyota for 17 years. Outside of brakes, filters, spark plugs, tires and oil changes the thing just ran perfect. Everything just worked. Then I sold it to a college kid and now it's running 21 years without a problem. A typical BMW from new to 10 years will have a lot of repairs and headaches.
I've had a lot of new cars. Mainly Ford Crown vics and a Dodge Durango. The last brand new Crown Vic I had the trans that went in 10k miles leaving me stranded. It was repaired and then worked perfectly. I also had problems with the Dodge Durango trans with under 40K miles slipping.
Since the majority of people rent cars for 2 to 3 years in general will not see problems of bad engineering or poor quality checking during manufacturing. If you buy a car instead of leasing you would be insane not have reliability as the number one feature you want.
