I work for an OEM mfg and have access to the dealership employees forum. It's amazing reading how many of them think all customers are trying to rip them off. I would love to blow off steam, but I'm absolutely forbidden to post on the board
Neighbor / acquaintence owns a local dealership. I have his home phone and cell phone numbers, which I've only used once for dealership business. His @#^% mechanic and #@$$@#$#@...#@$@#@#$ service manager decided to cut a critical part and then had the nerve to tell me I had to spend $1200 to replace it! They ended up fixing the part and funny thing, it was fixed with a $100 repair kit. I was happy with the final repair.
Fast forward few years later, after the owner in jest, harrassed me about buying a new car, the old one was 10 years old. Especially since he saw my new boat

He was right, 195,000 miles on my car and 140,000 on my wifes car. So we buy two new cars. From day one her trunk latch doesn't work correctly. We kind of live with it even after being in service twice. It finally gets bad enough and we take it in. Knowing that I'm friends with the owner, the service manager tells my wife she had an accident and we're trying to get warranty repairs for something insurance should pay for. Don't mess with the Mrs, she grabbed our salesman, literally, and dragged him out to the service area demanding the car be repaired! I called my friend and suggested he sold me a car that had been involved in an accident and wanted it replaced immediately, with one that wasn't fraudulantely represented. Repairs were attempted, although rewelding the striker pin to the body seems less obvious then replacing the "still" defective latch, <sigh>. Sometimes you just get tired of fighting. My lease expires in about a year, and I don't have any idea what I'm going to do

Hate losing the dealership a mile away, but they sure don't deserve my business.
Dealerships are independent businesses, but they sure have hurt OEM sales. I saw a report showing how much customer dissatisfaction hurts future sales, and it's phenominal. If it's produced properly, it has no reason to go to a dealer. If the dealer fixes it right, customer may be a little less happy, but they come back. F* up a repair on something that should have never broken, customer is gone. And GM, Ford, and Chrysler wonder why their sales are lower.
