In unmolested original form there's nothing wrong with them at all but 90% of the things have been absolutely ruined by random 19 year olds sticking various bits of tat to them, a set of -50mm lowering springs on 20 year old shocks, oversized alloys and with stupid, stupid exhausts. The noise they make is nothing short of ridiculous and can be heard from miles away.
Oh and cheap buckets for added effect. They just seem to have been the ned car of choice for a few years (around here anyway), I used to meet what I assume was a 1.4 every single day on the way to work when I had my MR2 turbo, without fail the guy decided to hang off my bumper at 40mph in second gear. To this day I have no idea what he expected to happen if I did put the foot down, maybe he just wanted to see the car shift I have no idea but the noise of his stupid, stupid sounding little thing went straight through me.
