What should I look out for when purchasing a used BMW M1?

I am thinking of buying a used BMW M1, but I am not familiar with the model's common issues. Are there any specific problems that I should be aware of before making a purchase?

Some common issues with the BMW M1 include leaking coolant, oil leaks, and electrical problems. Be sure to thoroughly inspect the car and have a mechanic check it before making a purchase.

In addition to checking for common issues, make sure to also check the service history of the car. Look for regular maintenance and any major repairs that may have been done.
