Unfortunately, I think there might not be any (though I have not been to M'Lady, and they could be the exception).
I have had Espo's Auto Service do most of the service to my VehiCROSS.

Many other owners have had their VX serviced by Sam, so (unless you are getting warranty work) you might want to call him.

Whatever you do, DO NOT take your VX to Evanston Subaru in Skokie. They were going to charge me $6800 for a new transmission (that I didn't need) when all mine needed was a new filter & gasket. They even had the balls to tell me I didn't have 2nd or 3rd gear anymore. Odd when Winter Mode worked just fine...
