Bought my Mig end of Jan 2009. Got it cheap (£360)Since then, spent about £700, including about £150 to £200 on tools. Was frustrating, but in reality, would have probably spent that sought on money even if I paid £800 for it. Basically have done service parts on the car, which you would have had to do anyway. Now it's running, happy bunny and chuffed.
Still got niggly bits to do. Think there's a loose wire for rear screen heater, ciarette lighter don't work, so can't charge phone and there is a musty smell coming from the heater or heater matrix. Found a pipe tonight, part of the heating system that appears to ave been repair by a jubilee clamp which is restricting the flow - me thinks that could be the proble. Others can be easily fixed over the next few weeks.
So, stick with it, they are great cars. Loads of power, loads of space, great work horse and look good
