So I just bought a CLK 350...
It shouldn't take three days for a transmission plate replacement. It's a what, 2-3 hour job? The guy told me they had to take apart the entire transmission and this and that, but I know that's not true, and figured considering that he was not a mechanic he was just speculating (unless their on site mechanic really is an idiot). Frankly the car seemed fine while I was there--and I really wanted to leave with it. I checked the car history and it seems to be in pretty great shape in that regard as well, so on one hand I want to believe it's just the transmission conductor, but the fact I heard them scrambling when I got there and mentioning the fuel pump and a few other things, well I don't know why it would take this long.
I'm going to call tomorrow, and wish I had the time yesterday. But what do you all think? If things go accordingly, what are some things I should have checked out to make sure?
First and foremost, unless you're an expert mechanic, it's important to get a pre-purchase inspection from a mechanic you trust when purchasing a used car, especially an older Mercedes. Otherwise, be prepared to be unpleasantly surprised with high repair bills.
The car as you describe it sounds like a questionable purchase at best. It might be worthwhile to inquire about cancelling the sale and getting your money back. Even if you had to pay them $500 (or more) to do it, it might be worth it to avoid likely future headaches and expensive repair costs.
If you really think about it, if there was an inexpensive or simple fix for the car's issues, don't you think they would have done that already? If you've already bought the car, they don't have much incentive to fix anything well. The only incentive they have is to fix it just well enough to get you out of there (which probably won't be a very good or long-lasting fix). I would get my money back and run, but that's just me. If you haven't yet paid for the car, I would definitely peace out. Sorry, just being honest.
If there's no way to reverse the sale, I would get it inspected by a trusted mechanic to see what you're dealing with and go from there.
Best of luck whatever happens!

I'd walk away from this transaction after reading about all the uncertainty surrounding this car. Surely there is another CLK out there for you somewhere that would not entail going through all that.
GL to you!

I would have walked away at the first broken promise. Buying an used car, of unknown provenance (regardless of paperwork), should always be done with the assumption that it has hidden problems. It is the salesmans job to convince the client otherwise, and that the car is sound and reliable. That car lot did an awful job in that front.
If it were me, I wouldn't sign or pay, before the car was ready for delivery. If I did, and I couldn't back out of the purchase, I would get from them a solid, written warranty (even if I had to pay for it), and then (and only then) inform them that, due to all the issues that arose during the purchase, I was going to take the car to Mercedes for inspection, and expect them to repair all issues that Mercedes detects. Maybe that would make them reconsider cancelling the sale.
If not, carry out the inspection (either at Mercedes or a good Mercedes specialist), and present them with the results. Who knows? Maybe the car is indeed in good shape...but then you will know that for a fact, and not just hope it is the case.
But, then again, that is what I would do. Your circunstances may be different.
In any case, good luck.


1. Potential balance shaft issue
2. Early 722.9 transmission
"transmission plate" probably means transmission conductor plate which in 722.9 combined with TCU (transmission control unit). In case of failure it most likely will require MB dealer labor since there is still very limited amount of shops which know how to virgin and recode 722.9 TCUs. Even this forum's guru Rodney had to take his car to a dealer and if I remember correctly he payed around $1.5k for that.
