VX220 wins. Obviously I found slight faults with both :) but while the ones on the VX220 seem to be mostly cosmetic (it's a high mileage car) the ones on the S2 felt like they were a little more expensive. *Especially* as I wasn't convinced that the clutch judder I noticed on the S2 when changing down was somehow the fault of the TPS...
Let's see how the negotiations on the VX220 pan out and/or if the insewerants have funny ideas about me garaging it.
