Expert Tip

Next stop was Cadillac. We explained everything to the service manager, they aligned it again and told us it was back in spec. I picked it up… and it still drove awful.
I bumped into Michael Sullivan and we talked about what was going on. So we brought it to Sullivan’s Truck, Auto & Collision Repair.
From start to finish, the experience was completely different. Great customer service. Clear communication. They test drove the vehicle themselves and confirmed what we were feeling. When we picked it up, they walked through the alignment printout with us in detail — something no one else had done.
The Escalade now drives exactly like it should. They even had it cleaned and ready to go.
Can’t say enough good things about the team at Sullivan’s. Professional, honest, and they actually fix the problem. Highly recommend.

From the moment I walked into the lobby, I was greeted with genuine smiles. The person I had the pleasure of working with was Pat. He was respectful of my time, listened carefully to my questions and concerns, and went the extra mile to make sure everything was handled correctly.
Even though my car was totaled, Pat was a perfect example of excellence and professionalism. If you ever need to take your vehicle to Sullivan’s Auto Body Shop, you’ll be in great hands with Pat and the rest of the team.
