My mercedes shop was installing a new transmission in my 1985 500SEL and during the test drive they totaled it!!!!

I don't have the details, they just called about 10-minutes ago. He said they were waiting for the police and then they would notify their insurance company.

Does anyone know what will happen as far as the insurance company setting a value?

The car was VERY nice but I only paid $4,000 for it. It became VERY nice after I put many hours of work into it.

What should I expect from the insurance company?

Thanks,

Ray
