If anyone hasn't seen a Cobra R yet, there's one in Plano at Middlekauf Ford. Middlekauf is off of Plano Pkwy. The Cobra R is on the car lift, so it's visible from Plano Pkwy.
I'm not a big domestic fan, but it looks pretty sweet.

 

There was a red Cobra R at the John Eagle Honda Days at Texas World Speedway back in February. I didn't watch too closely to see how competitive it is, but I still say, if you aren't worried about having a spec'ed car from the factory in order to race in a said class, then you can get more bang for the buck with those things by doing all the aftermarket bolt-ons yourself.
