You sound like me. I gave up my truck, our 2nd vehicle cause I was trading them in after the warranty period or lease with 6 and 10 thousand miles on them. In 3 to 5 years.
We dont keep the primary cars out of warranty. Not the game of chicken I like to play.
2008 Ford F150. 182,000+ miles. Only major repairs were body control module and rebuilt entire A/C. Changed oil every 3000 miles and transmission fluid every 60,000 miles whether it needed it or not.
