I know exactly what you mean with the "how much horsepower." I was at the gas pumps the other day and had several admirers. They did the requisite 'what is it?', 'horsepower', and 'how much did it cost?'. All of which I don't mind answering. I enjoy seeing other people admire the car.
Except for one guy who kept spoiling the fun by bragging his mustang had more hp and that I would need a V8 or V6 squeezed in there somewhere to keep up. He didn't believe an I4 190hp could post sub 5 sec 0-60s and would beat his mustang on the track. In the end I popped the lid and showed him the engine then showed him the 0-60 after filling up. All-be-it safely on an unused road. I still try to keep on the cops good side.
