Tried a few times to make an appointment online. Kept having issues not allowing me to do it. I was in the area by Mark, Christopher so stopped in and made the appointment myself for the following w Kept having issues not allowing me to do it. I was in the area by Mark, Christopher so stopped in and made the appointment myself for the following week. Took my car in just for an oil change. Made the appointment for 10:45 a.m. and was out by 12:30 which was the fastest service time I've ever had. When I brought the car in it was very dirty and the car was given back to me in the same condition. Was disappointed it was not washed so that's the reason for four stars instead of five. I've never known a dealer to give back your car dirty. More

From the very beginning, she demonstrated outstanding professionalism and clear communication, keeping me informed throughout every step of the process. Chelsea also went above and beyond by assisting me in securing a rental vehicle while my car was being serviced, which made a significant difference and added convenience during the repair. When I received my vehicle back, it was running like new. I am extremely satisfied with the quality of service provided and truly appreciate the level of care and attention to detail. I highly recommend Chelsea and the team at Mark Cadillac for their exceptional customer service and commitment to excellence. More
