Mark's Automotive

I took my car there today, he said he needed to do a computerized diagnostic, (about $68.00). Then he said it was the distributor. Then he called me and said it wasn't the distributor, it was the timing belt, which wasn't done well, and he was the one that did it about 8 months ago. Later I went to pick up my car it wasn't running well . I got charged $275.00 and my car stalled. If you did a computerized diagnostic why are you not sure whats wrong with the car, but you did charge me for it. And why is my car not working. Very dishonest!!!!
