What's the last date I can post this to to arrive in time for Christmas? maxis 10k From the VX release; "Twelve drivers, comprising nine motoring journalists and three Vauxhall and Opel staff, each drove a total of four hours, split between the two cars. Only one tyre change was required per car (to be on the safe side), no engine oil was consumed at all, and despite completing nearly 1,500 laps of the two-mile banked circuit with the cars’ throttles nailed to the floor, both cars completed the attempt with a mere 22 minutes downtime, in addition to refuelling and driver changes."
