Owner
First off, I really like this dealership. Tim Goss was my salesman who sold me my car. (Which he's amazing) I have had my car serviced there twice now. I have noticed that this time my car is a little rough when starting it cold. And I always let it warm up until it shifts down, it seems to be idling a little faster then when I first purchased my car and my first service. But all in all it's a great dealership. Thank you Tim for all of your expertise.
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".

We travelled about 50 miles to Laura Buick GMC with the intention of buying a used vehicle. Rob Larson was quick to sense that the used vehicle we test drove did not meet our standards. He invited us to test drive a 2025 Buick Enclave, which we ultimately purchased. Rob was very in tune with our needs and exhibited extraordinary customer service skills during our sale and follow up. Making sure we had a great experience with the Laura Family

great service,nice company
This is a great company to buy a car.they will get you ready in no time.I would recommend this to anyone.
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.
