My Supra understeers, it only oversteers with an excess of right foot, i'd expect something with such a large nose and an engine at the front to understeer.
What gets people is when the car behaves in an unexpected way. Lift off oversteer was a big issue for 205 GTis back in the day, loads left the road because it didn't behave like a front wheen drive car normally does. The FTO has the same issue, push it too hard and instead of understeer the back comes round, not right for a front engined car.
Electronics also cause issues and or make things worse. My mate nearly piled his mini cooper because it had the ESD stability thing on it. He's a great driver having done rallys the lot so pushing the car down a road it began a small slide, mate corrected it at the same time as the computer decided to apply the brake to one rear wheel thus over correcting the issue and producing a huge wobble on to the wrong side of the road.
He drives with it turned off now.
