So youve had a sh*t experience grow up and get over it. Yes its unfortunate and yes you arent alone but not all of us have had problems with the product or dealers. If you want we can all post up here and fill the forum with "my cars great and so is my dealer" posts, but i would have thought it would be more constructive to use bandwidth on helping the poor sods who have had bad experience by offering help and advice.
I work in the motortrade and i can tell you that ALL manufacturers WITHOUT exception have issues with build, design and staff quality. At the end of the day cars are designed built PDId sold and serviced by humans all of whom do make mistakes from time to time.
