Hmmm, well he's had a history of driving some slightly oddball machinery. Or nice machinery in oddball ways.
He's rallied an SD1 V8, raced a Rover 220 Turbo, plus messed around with assorted hillclimb and grasstrack machinery. The X90 cost him a grand about eight years ago or so. He says it's ideal for cheap motorsport, especially as he's running it in almost standard trim. There's a couple of "trick" X90s running in the higher classes (bigger engines, 4WD).
