I understand the post is supposed to be humerus. BUT, first we must define what is an old car.
Any car from the 20s or 30s is for sure old. But are 1980s or 1990s cars old?
My daily driver is a 1986 El Camino with 385,000 miles and my toy is an 85 911 with 196,000 miles. Both cars get a lot of compliments. With cars from the 80s, there there is always some project that needs to be taken care of. I can go to the garage and tinker on minor projects anytime I want.
I am in the middle of a oil change and valve adjustment on the 911 right now. I should finish that up today.
A couple of weeks ago I replaced the old R4 AC compressor for the AC on the El Camino. Back in the 80s they were made by AC Delco and lasted for years. Now they are all junk, made in China and my last one lasted 15 months. So I replace it with a Sanden compressor. That required a new bracket setup and some new hoses. It blows cold again.
My cars a my main hobby. Tinkering in my garage with the car on my scissor lift, I can spend the day doing minor things. I have done all the projects on my 911 and I feel sure driving it cross country. I have driven it too 41 states and Canada.
So is a 80s car an old car? Kinda, but not really.
