We did buy a car from them but the practices we're sketchy. We originally went in to look. We found the car we love. Then went home to sleep on it looked it up and it was $1750 less online. They wouldn't match and refused anything else to compensate. Then the week after we purchased the vehicle it starts having an air bag light issue. Took it in several times but it kept happening. Finally was told to go the Chevy dealer as it was only one of their used cars (it was a chevy) needed a new sensor. They refused to fix it. Worst car buying experience ever.
