From me, ABSO-F'ing-LOOTLY! I don't do drag but I do autoX and HPDE. I highly doubt you could rent it for the Xfire gents alone. Most events at Autobahn with the Lotus and Porsche guys are usualy 200-250$-ish for an all day. I'd be undoubtedly in if 1. Its under 250$, 2. It's either the south or whole circuit (north circuit alone is meh'ish) 3. At least 2 hours of actual track time. Say something like 4x45 minute sessions or something. Obviously the more the better.
