Bought my RX8 from the dealership in late 2009 - the sales staff were nice and helpful (although not too knowledgeable about the car - then again not many people know RX8's).
Service was a nightmare however, after 1 oil change I never took the car back again. After attempting to get another oil change done (booked way in advance, left the car with them for 3 hours) - I came back to the dealership only to be told they didn't have any RX8 oil filters and asked me to come back at another time! Their "RX8 specialist" there is also completely clueless about the RX8 and an incredibly irritating individual to speak to. Service Manager is a nice guy but its a shame the department is generally futile.
