Friend had a C6 vette, took it to the dealer to install a switch in console. It worked but was worn and looked bad. Picked car up and radio system wouldn't work, they said hmmm, its old and just went out. Cost her $800 to fix. Same dealer mounted tire backwards doing a flat repair, she showed them and they took it back in, brought it back with tire in same place. Then she bought a new camero at same dealer so the vette could sit some, hated it and traded both in for a 16 vette with 4000 miles. It was a local trade for an 18 model. Sweet looking car and drives itself down the road. Trans started shifting up and down when running low 70s. Then started at different speeds. I was guessing convertor locking and unlocking. Started idling rough and a little noise in rt cowl area on light accell. Wanted me to go in with her cause she had bad experience before, talking to her like a girl when she knows more about cars than manager does. Also had a draggy start and then a few no crank so I am thinking battery and key fob battery on no start. The advisor pulls history of car and I am looking at screen as is she, list starts up. She said print that out, engine had spun a rod at less than 2000 miles. I am telling her they wouldn't repair that in a vette, I am sure crate engine. Nope, had tech rebuild it, then later a flex plate for vibration. Salesman had pulled car fax when she was trading and only thing on the paper he gave her was one oil change at dealer. She is livid but I keep her calm and said give them a chance. Cust pay battery and $8 key fob battery, trans fluid flush and change to different weight per factory bulletin. No rough idle, or noise detected. Trans seems better, still idles rough and noise in dash still there. Picked it up on Tuesday and last night wouldn't start and threw a code on dash, started after several attempts and is now draggy again. Wanted her to put 200 miles on it to make sure trans is fixed. I told advisor t before she picked it up this car needs extra care and go above and beyond. Not seeing above and beyond yet, they have one more chance. No dealer I ever worked at operated like that. Car was even dirty when she picked it up, heck the dealers I worked at washed every car even if it was just an oil change. They don't want this girl to go off and she is close.
