No sherman tanks, hmm, well how about a Hummer? Get a nice big hummer with a seat cushion so she can see out the window and scoot up so she can reach the pedals.

ask her to picture herself going shopping with her girlfriends in a hummer, lol.

I too have wrecked many many cars, i had 6 cars before i was 18. and had a few more since then (now 21). so i kinda know where you and her are coming from.

A benz or volvo is a safer choice, since she cannot drive a big big car due to her size. Porsches are smaller and faster so she might enjoy one of those.

But if its a mercedes you want, hmm then get a 81-85 300D turbo. They are safe, not too big and with the heavy foot, you are mechanically limited to your speed at take off. they are very troublefree and long lasting.
