To be fair the figures are really close and the Scooby will lose more power through it's 4WD transmission, plus it's heavier, so I'd give the advantage to the MR2.... and standing starts are what the MR2 does best!
Wombat : I know what you mean with the Audis, my friend has an RS6, 450bhp with no lag and gearbox that lets it keep pulling between the gear changes somehow it doesn't ever seem to stop! Awesome experience!
