I unexpectedly picked up the Owens Corning Camaro at my local hobby shop today. Somehow it just fell in to my hands and drove me over to the checkout. It is a surprisingly good runner on Sport track with just the magnet removed and no other tuning. The front tires bind a bit on the front wheel wells, but other than that it seems to be a very good car.
I turned on my lap timer to see how it stacked up against a tuned Mustang on my small twisty course. The best lap times were identical at 5.4 seconds! I expect the Camaro to be the better car once I fix that front tire binding, so it looks like I'll be tuning that Mustang again.

This car wasn't even on my wish list, but it really jumped out at me when I saw it in person. No photos on any slot car site seem to do it justice. (including my shot above) The only downside is that they opted not to include the front spoiler, so I just may look in to fabricating one. Overall, I couldn't be happier with this impulse buy! :D
