So a while back I posted about the dealer not putting enough oil in my car and it started a slight knock(see here:

Well I took it to Classic Chevy in Grapevine TX instead of autonation where they messed up, and guess what? they couldn't hear the noise

so I'm like I'll come up there and drive you around to hear it. I get up there and the service guy rides with me and for some reason doesn't want to go out of the lot for me to actually get the noise to start, so he has me go back to the shop area and get the mechanic so he can hear it, I get him out of the lot and he FINALLY hears it after I go up and down the road/freeway and this guy tells me it sounds like the rattle from the exhaust service bulletin that was put out and I'm just not buying into it so I say "ok so basically what your saying is that it's not the engine? So keep driving it until something happens if it is the engine?" And he goes yeah. So we get back and the other guy comes up to me and was like well he says blah blah and your not under warranty for the exhaust so we can replace for $750....WHAT?!

I said uhhh no I can get a better sounding aftermarket for a little more than that no way, he got this mad look on his face when I said that and tried to push me by saying "well aftermarket are welded and these are bolt-on" I'm not dumb I know there are bolt on systems, duh. So he says well bring it back if you have any more problems.
So that was about a month ago? I've driven it some but not normally like before and today I get in the car to go down the street to the car wash since she was lookin a bit dusty and I turn the key it starts up and the CLANK. DEAD. Nothing.

SO, now I'm torn as to what to do, both dealers have been shotty with me now, the woman that sold me the car at classic was great but the service dpt seems to SUCK!
And btw I do have the whole thing on recording just in case someone tries to say "oh I never said that"
