No context and no restrictions, just go for it. I like a Mach 1 Mustang or a late 60s Impala - a la Supernatural if anyone has watched that show
Mine changes week to week. As a kid, I always wanted a TVR Cerbera after watching a Jeremy Clarkson video where one won a drag race against other super cars.
My dream car as a kid was always a Corvette Stingray, the mid 60’s early 70’s one, but once I was truly in love with it I discovered the s2 from the late 50’s (I think) which is beautiful. But I think nowadays it’d be the Celica GT four (preferably Carlos Saint edition) from the practical golden age of rallying. And more realistically if I was to have one last throw of the boy racer dice before I retire I do currently covet the Yaris GR four. Not only the most practical of the above, I could go out and buy one tomorrow if I really wanted to. (Not great for grandad duties)
As a child of the 80's I'd love a DeLorean as an occasional run about. Beyond that I'm not much of a car person
I owned my dream car - a red Suzuki Cappucino, 2 seat open top, 0.65 litre engine, max speed of 85 miles an hour but it was tiny, weighed nothing and had twin turbos. It could beat anything off a standing start. Gorgeous car... it developed an electrical fault that made the engine stop at any time, once at 75mph on the motorway. My wife got pregnant and so it had to go. I'd love a BMW Z4 now.
Had a few 'premium' cars (Merc, BMW), but always been disappointed in terms of reliability. Nice to drive and all, but I get put right off brands if there's it's problem after problem. Had a number of French cars that have been fantastic. But if we're talking dream cars, and not considering affordability, reliability etc, then I really like the newer Bentley Continentals. Quick, comfortable, classic British styling. Love them.
Always wanted a Jaguar XJ-S, even before Simon Templar got one. Iconic. Aston Martin has always appealed, as has a modern sport Bentley (convertible is a must). Quite Tory in my taste of cars, but unfortunately not Tory in my ability to purchase one. In my late 20's I was 'given' a Jenson Interceptor for a nominal value, to take away and do-up. Mrs Mac vetoed as we had nowhere to store said project. Likewise in 1998 I was offered an early 70's Triumph Herald to take away and do what I wish with. It only had 8k miles, but again, nowhere to store. If I could have any car from the past, it would be my Dads 1971 Triumph 2.5 PI. I can still smell the petrol and leather, and fondly remember long hot journeys to the coast in my shorts, ripping the skin of the back of my thighs upon exit. Happy days.
