Most annoying groups of car owners!
I've owned an SRT4. It was basically stock with some performance upgrades. It was one of the quickest cars I've ever owned. It scared the crap out of anyone who rode with me. I had a Honda guy rolling next to me in traffic, revving his engine and wanting to race. When I popped the clutch in 2nd gear and smoked the front tires while rolling at 20 mph, he changed his mind.
A well built turbo 4 cyl can put out some major power. But most of the cars on the road with all of the bling and the fart mufflers are owned by douchebags that think a 20 second car is fast.
