Bad experience overall. My car wouldn't start overnight so I had it brought to the Palo Alto Shell. The diagnosis itself cost $130, then $500 of repair. After that repair, the lights of the dashboard wouldn't switch on and they refused to recognize it was their error and wouldn't fix it. The car worked for one more week and then started again not to start. I had to repair it again and brought it to another auto repair, which this time fixed the car completely and fixed the dashboard lights.
