Pretty much everything from what I remember, Had a few mates get them when they were new ish and each one only kept it for about 4-5 months due to unreliability (springs cracking, shocks giving up, and huge ammounts of electrical faults, plastic trim falling off on every speed bump etc etc..) One of them even ended up buying the v6, and that was even worse, in the 9 months he owned it he only got to drive it for 3. They may have just been unlucky but thats 4 friends of mine that have owned them and hated them.
I'm probably going to get alot of stick from fans for this, however, i'm speaking from experience of helping friends fix them every other weekend, or picking them up from the garage they have just dropped it off at.
As has already been said, there is so many for sale at such cheap prices for a reason.
