It's OK to be a car guy and not care about uninteresting cars. I haven't kept up with new cars for about 15-20 years. I still go to a new car show (Rochester NY) every year. Don't ask me why I go! Most of the cars I see are unfamiliar and quickly forgotten! They all just kind of blend together by the time I get home. Vintage cars shows are where I belong.
I doubt I would drive a new car if cars were free. I don't find them enjoyable. Maybe I just haven't driven the right new cars.
A lot of my favorite cars are from the mid-80s to the early 90s. But a quick flip through a car magazine from that era reminds me how many cars I'm glad I forgot about. They weren't all good or interesting!
I've been a lifelong car guy too. Practically memorized every page of every car magazine or book I got my hands on. My first word was car.
