A dream car? Make mine a 1962 Ferrari 250 GTO Berlinetta. Only a few dozen were made, but it was essentially a Formula 1 racer with an aluminum body so it would be legal for the street. Fantastic hp for its time with its 3 liter V12 engine. There was a time when I could have bought one for $10,000, but I felt that was too much money. Now they sell for around $20 million dollars. OK, big mistake on not buying it.
The Delorean was a nice concept car, but had poor execution and was very underpowered. In the Back to the Future movie, it had to get up to 88mph, if I remember correctly. In real life, it had trouble doing that. I passed on buying one new, thank God, and later looked at a used one with the intention of putting a different engine in it. But when I discovered the massive amount of troubles in the second car, I passed on that as well.
