Not yet. My local mechanic put the A/C together, the local Subaru guy from whom I got the motor is also willing to work on it and, if need be, I'm less than 100 miles to RMW.  

Routine maintenance is easier than the VW engine since it's easier to get to the oil filter and bolt. The stainless exhaust and coolant pipes are better than OEM.
