Left door's interior was very dusty. They could've have cleaned it up. Repairs took longer than I thought, however my car looks great.

Tim was super helpful and I loved that they were able to schedule me in so quickly. There were understandably supply issues and it took some time for parts to arrive so I’m glad my car was still driveable in the meantime. I missed my original drop off appointment and Tim was thankfully able to get me in the following week. Tim and his team were a delight and I highly recommend.

We are waiting to hear when we can bring the car back for installation of the clear bra piece. As it's a 30 minute trip we would like to have a time set up when we could come up & wait while it's applied.
