I was always amazed where my 4 cylinder cortina would go, so I'd put a set of muddies on it and carry a winch, that would go 90% of the places you can get in a patrol ( using the winch of course ).
As far as the question goes though I'd have a fleet of impractical vehicles, all of them preferably offensive.
edit: none of them would be a toyota however. And that's coming from a Jeep driver. I only want vehicles with character. Which means there'll only be Yank, Pom, Italian and Frankenstein Jap cars in my garage!
Back to "Street Machines" I guess I'd do up another car for sure.
I'd be tempted by an R34 Skyline but Corvettes are ticking a lot of boxes and in line with Yom the corvette would have to have loud and offensive lakes pipes and a big block.
