I've bought 3 cars over from Bobby Rahal over a ten year period and had service there for as long as the cars were under warranty.
Plusses:
Sales. They are very straightforward. They can answer technical questions about vehicles. They offer a good deal from the outset. They don't try to get you to pile on extended warranties, extra coatings, etc.
Service. Always competent. Loaner cars available. They wash the car as part of the service.
Minus:
The service is expensive, but that's just the way it is with Volvo service. Once I've had cars go off warranty, I take them to my local garage.
