I give this little garage an excellent rating. I blew a spark plug and needed to have the hole bored out, re-threaded, and an adapter for the plug installed. Estimates, went anywhere from a "couple of hundred, to $1500" if the head had to be removed. The mechanic did it for 10% of the estimates from the other garages and engine repair shops. Being on a fixed income, this was the best present I could ask for.
