McGrath Acura of Morton Grove

I bought 2015 Acura MDX on December 13th 2014 from this dealer. I spent 4 hours at the dealership and finished all the paper work. They gave me the temporary registration for the new vehicle which is valid till 1/12/2015 and said I will get the title documents and registration plates with in 2 -3 weeks. I was so happy with their service and left the dealership with my new vehicle. On January 9th 2015, dealer called me and said there was a mistake with the paper work and they have to do it all over again (re-apply the loan and all) and asked me to sign the documents which they are going to mail me soon. I asked about registration plates since my temporary registration is expiring on 1/12/2015 and the dealer replied plates are ready once they received the documents they will mail it right away. On January 12th 2015, I received the papers, signed it and mailed back to the dealer on the same day hoping to get the registration plates soon. On January 13th 2015, dealer received the documents On January 14th 2015, I called dealer 3 times to check the status of the title documents and left voice message but no response (temporary registration got expired on 1/12/2015 and was not able to drive the car) On January 16th 2015 I called 10 times (counted my call log) and left several messages to check the status of the title documents and plates and no response. (temporary registration got expired on 1/12/2015 and was not able to drive the car) On January 19th 2015, After calling so many times finally the dealer responded and said it will take 4 – 6 weeks to get the registration plates and nothing they can do with the expired temporary registration and I have to wait till I get the plates ( (temporary registration got expired on 1/12/2015, so I can’t drive the car until I get the registration plates) Exactly after two months of the purchase date (December 13th 2014), and one month after the expiration of temporary registration (Jan 12th 2015) finally I received the papers and registration plates on Feb 11th 2015. I was not able to drive my new car for almost one month and wasted so much time dealing with all this. By the way on the title papers the purchase date is mentioned as 1/2/2015 but the actual purchase date is 12/13/2014. Lessons I learnt: 1. They don't know how to do the paper work 2. They lie 3. Worst buying experience in my life 4. Unfortunately couple of people (sales person who sold me the car and the general manager)who was trying to help me out left the company and others doesn't take the responsibility and addressed the issue. 5. Two of my friends bought their MDX after mine from other dealers had no issues with their purchase and was able to drive their vehicles since day 1. So, before buying any car research about the dealer too not just the car.
