Sounds like this dealer needs a lesson in customer service. Is the dealership the only one within a 100 miles?....seems as if they feel they are the only game in town, so they have the attitude of "take it or leave it". This will come back to bite them in the future. I bet the local Chevy and Ford dealers are getting additional sales due to these clowns.......write your letter, it may or may not help....but it will make you feel better and who knows, maybe they will get their act together.
