| Re: How can you tell if a cts has the sport package or not??
Easiest thing is to just look at the wheels. If they're 17" or 18", it has the sport package. The 17s can come painted or polished. They're fairly easy to distinguish from the 16s because the lines of the spokes on the 17s continue right into the center of the wheel, whereas on 16s there is a center "section" around the lug nuts that's smooth and round, and the spokes come out of that. Just focus on the middle of the wheel and you'll see what I mean. |
