Don't forget the ability and willingness to work on them in a parking lot, on the side of the road, in the middle of a date. . . . They will break down. You just have to be ready for it.
Thank God the texaco quick stop we blew the PS hose in had type F--all dusty and in the back of the racks. We bought it all. My wife and I took turns dumping in the PS fluid all the way back home.
If you have a wife/husband/significant other, a positive attitude from them helps too. My wife is the best---she loves both me and the Mustang and is willing to deal with both of us, warts and all. I dated a woman years ago in college who didn't like my MGB because, with the top down, it messed up her hair. I hated to ditch her as she was a beautiful red-head, but, well, cars are such a part of my life, they have to be at the very least tolerable by women I dated. My wife has helped me bleed brakes at 11:30 pm before a show. She's a peach.
So, long answer to a short question, your car will impact more people than just you.
