Mike is just about the best mechanic I’ve ever encountered. He is a straight shooter and will save you money if he possibly can… on good used parts or whatever solution he knows would reliably work, but may not be the obvious answer to the problem. I went to him because he was able to fix a squirrely issue w/my sister’s VW Golf diesel TDI. I have a Subaru Outback and I couldn’t be happier with the help he offered… at a very fair rate for the time he ended up spending. You won’t go wrong with GCAS for sure.
