My best mate has a 3r. Lovely car, v quick he hasnt had too many problems, apart form it doing a few belts. Servicing is fairly expensive but it always will be for a car like that.
They get seriously hot in the cabin and the windows only go half way down which is a little annoying. They do have aircon though.
Been to le man in it for 3 years running now and even drove it this year
They are a very quick car but the gearbox does take a bit of getting used to. Seriously quick though and if it had a slightly better gearbox would have no problems keeping up if not going passed my mates fezza 360 cs.
