Mike and his team at Schearer's do great work and only replace what needs to be replaced to solve the problem rather than replacing everything that could possibly be having any bearing on the problem. As the owner of an older BMW, I appreciate this conservative approach. Replace the most obvious, test to see if it works, if not, go on to the next possibility. They are honest, have integrity, and value their customers.
Schearer's is my place for non warranty work.
