Mercedes-Benz of Walnut Creek

First I purchased my car. Went in with a set price and did not budge. The salesman was [violative content deleted] from the word go. second after I got home they called me and asked if I had the keys to my trade in. I said no I gave them to Ali. No calls for about 2 days. next call, hey by chance did you give us the title to your trade in. I told them yes. the finance person had it all in front of her which included the keys you called me for a few days earlier. Oh by the way I told them. I need you to take off the double change for the documentation filing fee you charged me for. You only drew up the contact once not twice. They said they were sorry and have to redo the contact. may not sound like that much but add up 50.00 plus interest plus 5 years. that 50.00 will end up costing me over 600.00. They redid the contact and told me everything was the same except for the extra filing fee charge. now get this. Because they had to redo the contact once again because THEY messed it up from the start. They charged me another 50.00 filing fee which is exactly why I had them fix it in the first place. I mean WTF! I told them hey! by the way. do you want to take off the 3 year warranty you added on here for 2,550? She said OH how did that get on there? Told her I don't have a clue but I'm not paying 6,000 (full length of the the car contract)for something as junkie as those cheap after market scams that you just added on the contact. OK so while I wait for them to redo it a for the third time. I went in to sign the contact and guess what? You got it. another 50.00 charge for filing and documentation fee for which they [violative content deleted] up from the start. After the fourth time they got it right. Don't know if they ever found the keys or my title and to be honest. I don't care if they ever do :)
