If there is another dealer closer than fox, I would use them for simple stuff. I also have a print out I post on the steering wheel that states how to lift the car. I do not need to do this with Fox as Critterman has educated them on how to lift a sol and they will never screw it up.
If you need a major such as a new dif. or even your seal, I would take it to fox. There are just too many things they can screw up if they do not follow the procedures correctly.
Further away, there is a dealer in Manasas Virginia that has sol repair experience.
