So far so good.
I was rear ended on 10/2. I brought my car in on 10/4 because GEICO said if I used this shop that they would guarantee the repairs for life. I was told the $1400+ of repairs would take until Monday or Tuesday. I was called at 3:30 on 10/5 and told my car was completed. I couldn't make it to the shop until the following day. I picked up the car in the morning.
The only thing that was disappointing was when I noticed the Sun Devil Club fork I had on my tailgate was removed. They had to paint there, so it was sacrificed.
There may be an issue with the tailgate not being 100% centered, but only time will tell. I will update once I've had my repair back for enough time to gauge its ability to hold up long term.
One nice thing about this location is they have both a GEICO rep and an Enterprise rep on site. I was able to have my claim estimated and get my rental car without leaving the premises. The whole process took less than 50 minutes.
