Ok, money's no issue, what 10 cars would you have in your garage?
To get the ball rolling, here are mine:
Bugatti Veyron (253 MPH. 'Nuff said.)
Alfa Romeo 166 (Looks damn cool)
Cadillac Seville STS 1992-1997 (Always have liked the styling, and owning one hasn't changed my mind about them in the least)
Ariel Atom (Just look at it!!)
and in action...
Ferrari 599
Cadillac Sixteen (just... O....M....G.....!!!!!)
...Actually that about covers it. I don't wanna park my 6 cars too close together in my 10 car garage :p
