One Low Price. Plain and Simple!
----- When we surveyed our customers, we found that over 75% do not like the traditional negotiating process that happens at most dealerships. So we decided to do a couple of things .....First: We put our VERY BEST PRICE on every vehicle 24/7......Second: None of our salespeople get paid a commission. They get paid the same whether you by a $2000 Car or a $50,000 car. ----- Every dealer knows what their lowest possible price is, they just hope you will pay more. Every dealer knows what your trade in is worth, they just hope you will take less. -----

I have decided that this will be the first and final General Motors (GM) product that I will purchase. The air conditioning failed at 60,000 miles due to a problem with the condenser. At 65,000 miles, I had to replace the transmission because it was causing very rough shifts between gears 1-2 and 2-3. Unfortunately, at 120,000 miles, the transmission is once again exhibiting the same issue it had before it was replaced. Additionally, I was unlucky enough to have a truck that experiences paint peeling on nearly every body panel. This is especially prominent in large sections near the windows and rear doors. Needless to say, I will not be making this mistake again.…
