mmmh...very very tough choice.
I'd say a Dauer EB110SS with power kit. Basically, it's a Bugatti EB110SS with 750hp. Always loved that car.
Then a neat truck like this one here
And if trucks are forbidden, then I'll simply take an Aston Martin V8 Vantage Le Mans Lagonda Shooting Brake. Never existed as a Vantage version, but at least one was custom built in standard V8 form. Just imagine an estate (break?) 4 door version of an AM V8 Vantage. It would kinda look like this...
