These LeMans cars are the reason I started collecting cars in the first place. I was watching a lot of GT races on the Speedvision channel and I got hooked on the LeMans races. Then one day at the store I saw some of these cars for sell, and since I've tried to buy every one that I can find.
Celica Pikes Peak, 1997 - Hot Wheels
I got this one at an antique mall store for $1.99.

UPDATE: (3-29-08) I got this Pikes Peak Celica at the store recently. They also have it in Red. It's a Hot Wheel of course.
