thermostat hosuing either leaks. either new one or sealent. not a major problem
dmf ive heard can be a problem (depends how much you rag the car i suppose)

touch wood ive only had like a couple of minor probs.

had the car nearly a year now and love it.

its nice to drive, wicked handling. gearbox feels solid and awesome. but doesnt feel 170 horses and probably aint.

all in all. love it
