1992 GMC Typhoon
Pocono Raceway - Miller Genuine Draft 500You have to wonder - is the back hatch window open because:- They opened it on purpose for just staying more cool
- They pushed the open window button by accident when using the light bar control
- It popped open during hard acceleration to get on track (yes, it happens)Still looking for this Typhoon. Have info on it?
