My uncle has a 1992 400E that is a true RENNtech. 6.0 conversion performed by RENNtech when the car belonged to RENNtech. The car has 175k on chassis and 75K on the motor. The car has never ever been in a collision, fender bender, or anything. All original, all straight and true, NO STORIES WHAT SO EVER. White on gray. According to RENNtech it puts out 420-430 hp and 420lbs-ft of torque. my uncles had the car since 1999.

Its for sale now, but we dont know what its worth. Its exterior as it sits is a 9 out of 10. and the interior is a 9 out of 10.

Im a BMW guy and dont know what/how to value this car.

Whats it worth?
