After recovering my car from a theft, there wasn't much left. My friend and I built a new motor and I put a lot into new suspension, new exhaust, reupholstering the seats and more. The car drove okay, but something felt off. I needed another set of eyes, and there are no eyes I trust more than Import Sports Performance. I've been taking my car to them for almost 15 years. They found the problem - an unbalanced crank shaft - and put things back together so that it was better than new. I'm still breaking in the motor, there's almost 700 miles on it, and I know that its right. Even with all my experience the words of Dirty Harry are still appropriate, "A man's got to know his limitations." When you've reached your limit, take your car to Import Sports Performance.
