Didn't want to check top speed and don't wanna find out either, don't even want to drive a load of crap like that ever again, I'd much rather go on a mountain bike instead, no still not an Indian/Chinese one
As for it nearly flying, very true as that boxy shape seems to make the car very unstable, after all it's a design from the 80s. Good you let him go cuz yes, the brakes in it are so useless at that speeds you don't really get any sense of slowing down, and would obviously have rear ended you. What were you driving, the E46 or March?
@virensti - The rear has semi independent suspension on the Yaris/Belta, but you're right the tail does step out at high speeds with a very light rear end, also think the shape is generating some amount of lift. Not very safe or easy to control at high speeds, and a functional spoiler would be a good addition even though it's a FWD.
