Rented the Shelby Hertz last weekend, this should be standard for rental cars. Seat of the pants tells me that it is more like 330 at the rear wheels, rather than at the motor. Handles great and sounds better. Took a 270 degree off ramp at about 80 mph car handled it well, at the top of the turn I put my foot in it and the car responded great. They don't let you turn of the traction control, but you can still have fun with it the 355 gears seem to help it a lot. It is still the best car I have ever rented. It takes 25 mins to go through thre check list before and after, the bottom of the check list doesn't say anything about not racing or pushing the car, it says "this vehicle is intended for your driving enjoyment, please obey or laws."
