ALWAYS have the car re-aligned after you purchase it. Include it as part of the pre-inspection. And then again at the 2500 mi mark. Because the suspension isn't fully settled from the factory, it tends to knock itself out of wack.
I remember when Mario Andretti was doing a top speed test for Car and Driver a few years back with a RUF that just came over on the ship.
He said that he was losing speed on the banking b/c the car was a few degrees out of alignment. They put it on the rack and sure enough - just a touch out of alignment! He picked up another 5-7 mph on the top afterwards!
Best of luck. Remember to get it checked at least once per year at a minimum.
