I will no longer take my car to Parkway Ford as well, even with the extended warranty which I purchased through them; I'd rather take my car to someone else and pay the $50 deductible. I started going to Expressway Ford in New Hamburg, even for oil changes. It is a bit of a drive, however.
I had my water pump replaced by my private mechanic (who is within walking distance of my work) last year and he was very impressed with how easy it was to deal with the extended warranty company, so I'll be taking my car to him from now on.
