Some years ago the window mechanism on a Ford failed. The local dealership wanted £400 to fix it. A quick Google, £11 for a repair kit and 90 minutes later it was fixed. It seems the norm these days that everyone is out to screw you and honest business is a thing of the past. I find it satisfying, if not a little disappointing, but I now treat all companies as the enemy.
I should add that I've experienced similar lying/cheating behaviour from my local Land Rover dealership and a local independent in dealing with my Range Rover.
