Oh right, if it's just 60 seconds to make your mind up, it would be this (there's no way I could pick a best car ever, I'd have a long list...)
90's Virage Vantage, in this colour
With Magnolia leather
I've lusted after this since it came out when I was a teenager and it still gets me hard!
Original 550 bhp version rather than the later V600.
I do sway a bit towards the older model Shiny mentioned though, as time goes on.
Oh, BTW
@Shiny, I've been in one of those. Le Mans limited edition convertible version, in dark metallic blue with magnolia leather and paint matched piping. Was out in it for about an hour on a sunny day with the roof down...

Exciting and pant wetting isn't really the word...
