Hey Rob,
Roadrunners is a car club in Luxembourg, some very nice guys. Not alot of mopars. the best place to see mopars(and old muscle cars in general) are at shows in belgium and holland. I was stationed at Spangdahlem for 3+ yrs.
Is there anybody from the Eifel on here, we'll be traveling to germany the end for Feb. to visit wifes family. I lived there for years, you'd be really surpised how many old muscle cars are around especially in holland, luxembourg, etc.
