BEWARE... We recently purchased a low mileage special edition 07 Chevrolet. A check engine light came on so I wanted it to go to a reputable dealer to be serviced. I knew they would be expensive, but felt it worth the investment on this vehicle. Services were expensive relative to our other service center but we authorized repairs based on prices provided over the phone, including total drive out cost. We were very surprised by additional charges in excess of $200 when we picked up the car. They offered lame excuses but would make no adjustments. We were forced to pay and are now working with credit card to contest charges.
Adding insult to injury, it soon became apparent that they sold our info. Within days our mailbox began to fill with extended warranty offers from everwhere, Onstar and satellite radio offers. They are still coming more than a month later. We purchased from a private seller, so there is no doubt about who sold our info.
I am overwhelmingly disappointed in what I thought to be a fine, upstanding, reputable dealership. I will never step foot on the grounds of any Jim Ellis dealership again, even though they are so convenient to my home in Dunwoody.
