These guys are always busy and I know why, they are honest! I went in with problems to my vehicle. They hooked it up to their computer and got a code they did not recognize. They spent several minutes researching this code and then told me I would be better to go to the dealership. I tried to pay them for the work they had done, but they would not let me. Because they could not fix the problem, they were not going to charge me. We have used them for other repairs to our other vehicle and they have always done an outstanding job.
