When I was a kid I wanted a Countach or an F40, till I got past the age of 6 and figured out how expensive they were... still wouldn't pass one up if I won the lotto, newer cars be damned.
Growing up in woomera there was a dude who lived close who drove a lime green and black SLR5000.... it was the most impressive thing I'd seen at the time, still got a soft place for toranas. Them and 67-73 mustangs. As well as the AC Shelby Cobra - for looks alone, let alone the power.
Modern Cars? Audi R8 or anything by Pagani. Too bad I ain't a millionaire.
