Thank you for taking the time to share your experience. First and foremost, we sincerely apologize for the frustration and disappointment you experienced. We understand that traveling such a long distance to purchase a vehicle requires significant time, planning, and expense. Unfortunately, there were breakdowns in our communication and vehicle preparation, and we recognize that we fell short of the experience you deserved and the standards we hold ourselves to. While we did refund your deposit, we understand that this does not make up for the time, travel, and inconvenience you experienced. We take responsibility for where we fell short and are reviewing our processes to improve communication and prevent similar situations moving forward. We genuinely appreciate your honest feedback and sincerely apologize that we did not deliver the positive experience you expected.

Scheduled an oil change which was easy to do. Oil change was quick and I like that they completely check over the truck. Very pleased with the service. More
