What should be checked when buying a used BMW M1?

I am interested in buying a used BMW M1 and want to know what specific technical aspects I should be looking for.

First, make sure to check the engine condition thoroughly. Look for any signs of leaks, abnormal sounds or vibrations. Second, check the transmission and make sure it shifts smoothly. Third, inspect the suspension and brakes for any wear and tear. And finally, don't forget to test drive the car and see how it handles on the road.

In addition to the technical aspects, it's important to also consider the car's service history. Ask for any maintenance records and make sure the car has been regularly serviced by a reputable mechanic. It's also a good idea to get a pre-purchase inspection done by a qualified mechanic.
