I've had my second MX83 now for 6 years. its done 225k I had Head gasket, heater core, radiator, A/C dramas with both cars but they were general maintenance related problems from the previous owners. Don't worry about engine swaps unless you want more power http://users.bigpond.net.au/reanimotion/toymods/Wh atGoesWrong.htm Basically a damn good car
