NEVER!!! We will never go back. Car would not start it would turn over but not start. took it to them. Asked to see why it would not start. All the tec did was check compression one cylinder was at a varied range. Recommend a new engine. 4000 for a used engine with 100,000 miles. existing Engine has 67k. We took the car home.(They did not put the old plugs back in after check) Changed the plugs charged the battery and it started up. Still running now.
