I would first find a better mechanic. I'd bet good money dealers have overcharged you for parts and service. If you search the Drive Accord site, there are a lot of posts about where to get better prices for OEM parts. Since you're a "stickler for maintenance," that makes you an easy mark at a dealer. Keep that to yourself. I worked at a Mercedes-Volvo dealer in another lifetime, and I know their antics. I think your biggest problem is lack of decent, honest service.
