It's easier to answer if I don't think about it for more than two seconds, but I've experienced the true colors of my childhood "dream cars". They aren't all that.
I've driven an early 2nd gen Camaro. It's boring AF, and I'm not even a Chevy guy. That was all the experience I needed from that. I own a Grand National because it was my favorite car ever for my whole life. It's become a classic, and people who know what it is tend to get really excited to see it. I just hate how laborious and expensive it is to service, and BOY does it need a lot of service. It also breaks and tanks in value with every mile to the point where I don't even care to drive it anymore. It's cool, but as soon as I find a buyer willing to give me a good chunk of change for it I'm taking the money and running. For a little while my "dream" was to own a Volvo 242 GT, but half the reason I love old 240s is because of their stock reliability and all the fun activities with a wagon. 242s are slow and not even a wagon. Maybe I'm looking for a new "dream car". Will that ever happen? Doubtful. I'll never fall in love with a new car like I do with old iron. Today's cars can make as much power as they want, but I don't think I'll be too interested in them for another 20 years.
I've come to a conclusion. There are 0 cars in factory form that I can call my "dream" car because my car hobby is a bit different from most. My track record shows that I have the most fun with worthless cars that are destined for the junkyard. It's not about being flashy or even being "fast". There's just something very satisfying to me about taking an old POS with no right or reason to be on the street and turning it into something that enthusiasts would actually line up to buy. It takes a while but it's kinda fun to look at a car and realize that I've been through almost every single nut and bolt on the thing and still trust it to barrel down the road at 80 mph. For example, I wanted to build a racecar I chose a totally clapped out V6 Camaro, kept the V6 in it, and replaced the floors. It turned out way better than expected and it's not even close to done. When I think of an fun and reliable car to take on road trips, I think of a 30 year old Swedish station wagon. What's wrong with me?
I guess I don't even want a dream car. I'm perfectly happy with driving and building my rusty dumpsters. I've made big enough mistakes with car buying to realize that no car is ever exactly what it's cracked up to be.
