I was an extremely wonderful experience to work with
I was an extremely wonderful experience to work with Chris in the purchase of my new SUV. I would recommend Henna to anyone who is looking for a new vehicle. Anthony made the purchase process very easy.
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.

Jimmy was our sales associate, and he was nice, straightforward, and answered all our questions best to his knowledge..He let us drive the vehicle longer to make sure we could see how it was running and detect problems..Luckily we had this type of vehicle before and knew what to expect as they age..On our first mechanic visit he said that there were no major problems with it so far..We are so happy with the price and the condition of the van
