They ripped me off for over 6000 miles on my lease and claim i wanted a lower mile option which was never discussed with me at anytime. Now they want to charge me thousands of dollars to change it. I reached out to the owner who didn't even have the decency or time to personally respond to my call he had a manager offer me help with a new lease in 3 years. Pretty sure i wont be returning to the dealership for the rest of my life, speaks volume to the character of these individuals. I basically have a car that i am paying faithfully every month and can't really drive. Real bad place!
