I've only let 1 person drive mine and that was my dad on the night I brought her back home from where i Purchased the car.
He basically hopped right in (I owed it to him as I drove his supercharged vette a couple of months before)
Did I mind him driving her? - Not really
Did I mind him taking her straight to 140-150 leptops the 1st bit of straight road he came to, with me as a passenger - YES!! That was frightening!! But was priceless when he said "F:taped:CK me this is a bit too quick for you isn't it?!"
Wouldn't let many other people drive my car, if any. As said before - it would be like someone 'borrowing you girlfriend" to me.
Does anyone else find that as a passenger you are sometimes trying to push your 'imaginary break pedal' ?
