I understand your view, sort of, but I'm introduced by my friends as "the guy that drives his car until they don't make parts for it any more".
My current DD has 288K+ miles on it. Since it went out of warranty in 2002 because of mileage I have spent exactly $2,342.76 on non-maintenance repairs. So, an average of $234.28 a year doesn't exactly a new car payment justify. (By the way, this a Chevy Astro, not some precision made German machine).
Doing a quick count, I've owned 6 new warrantied cars over 3 decades. Of those, none had a major repair during the warranty period. Sure, they had some minor trim repairs that sort of thing, but it was all stuff I either wouldn't have had done out of warranty, or I would have done myself.
During that same time, I've also owned a
lot of used cars (including the above mentioned Astro that was purchased while still under warranty but with 16K miles on it at a substantial discount off new). None of them ever cost me more than $1,500 a year in repairs, and as far as I can remember none required repairs in the first year of ownership.*
My rule is once a car costs me either 1) in one repair more to repair than the Repair+Unrepaired Cost than the car is worth, or 2) repairs in one year exceed the value of the vehicle I start looking for a new car.
(*I'm excluding the the first group of $300 cars from that statement and the Ferrari since I only owned it for 2 days and never really drove it
)
