Ok, for just shy of £10k what would you have done?
Didn't that Astra guy get a LS2, box, rear axle and bits for something like three grand? Add a couple of grands worth of suspension, maybe a grands worth of brakes, allow another thousand for building the transmission tunnel, engine mounts etc. etc., keep £500 back for stuff like essential body mods and spend the rest tuning the LS2?
