They did exactly like they said.
They did exactly like they said. The saved me over $2500 over the next closes price. The delivery was flawless and respectful. When buying a GMC truck this dealership needs to be on the list.
Great First car
The 2003 Grand Marquis is my first car I have owned. I can honestly say that it is a phenomenal car. It is quite comfortable and, to quote one of my friends, "god xxxx that car hauls' xxx".

Ford never should have stopped production!
For many years I have purchased Crown Vics and Mercury Grand Marquis. The Mercury Grand Marquis is a step up in quiet comfortable ride and interior quality. On the surface, both the Ford and Merc look very similar, but there is noticeable difference on the road. Most recent trip to California in the Merc gave us 25MPG at 65 to 75 miles per hour. Just a suggestion, buy only the Crown Vic or Mercury 2003 or above. Cars 2002 and older have an inferior plastic intake manifold that is prone to failure at about 100,000 miles. About a $1,200+ repair. The 2003 and above plastic manifold has been aluminum reinforced. Too bad Ford has discontinued both the Ford Crown Victoria and the Mercury Grand Marquis. They are missed by many loyal customers.

They treat you like Royalty!
I have purchased three vehicles at this dealership over the years and I will keep coming back because: 1) they are honest! I did my research online and was able to build my deal online and I had no surprises!!! Zero! The price I was quoted was the price I paid each time and they even found me some additional discounts! 2) They treat you like royalty no matter what! When I purchased my first vehicle my credit was crappy. They were able to get me in a new car and NEVER EVER made me feel like anything other than royalty! Two vehicles later, credit is great and they they still treat me like a million bucks! 3) The quality of support and customer service is unmatched! The sales team is wonderfully knowledgeable and honest. Never pushy and very friendly and respectful! I have tried to service my vehicles elsewhere only to wish I never had. Honest folks with exceptional service that treat you like royalty! What else can you want?
