I totally understand what you are saying. However, in my (rather short) experience with cars, I've found out that when you are a meticulous car lover, you can't help yourself but become paranoid every time you leave the car alone in a car park, or it gets dirty, or you need to park it under the hot sun for several hours no matter what car you own. I don't think the problem is which car we are driving but how much we care about our valuable things.
When I turned 18, I inherited my father's 12 years old BMW 323i. I worried more than I should have every time I had to leave it unattended. Then I thought it was because despite its age, it was still all shiny and beautiful, and I didn't want to be the one to spoil it. Then, I got a brand-new Mazda Miata (which I still own, together with my Cayman). I also became obsessed with the car, but of course this time it was a splendid brand-new vehicle and I really was in love with it. Then, a few months ago, I got the Porsche. Now I use both (718 and Miata) as my daily drivers, 'cause I don't want to put too many miles per year on neither of them. And of course, now I have two cars to worry about at the same time. I don't think the car I drive is the problem. I am the problem. Even if I had a Prius I would polish and give it love. 🤣
Many days I wonder why I would have two "useless" cars in my garage. I might as well just get rid of the Miata and enjoy the 718 every day. Then I remember there are many places I wouldn't want to go to with a Porsche (I'm not happy at all to take the Miata to such places either, but it's more modest than a red 718) and realize I can't have only the Porsche. Then I start wondering if I should trade the Miata for an inexpensive and inconspicuous little car, but then again, I remember I would still worry about that little car all the same.
Two fantastic cars sitting in my garage but when I have to go shopping or take my GF to a restaurant, we always end up driving her boring 95hp Opel Corsa (Vauxhall for the Brits)
