Antigonish Wheel Alignment

I vowed to avoid going back to Antigonish Wheel Alignment, when an oil change on my SUV was nearly $100 (dealership cost $60). Yesterday the alternator went on our 2011 Santa Fe Sport and we were in a pinch so I had Antigonish Wheel Alignment do the repair. The owner quoted the part price around $300 which was fair. I've had alternators replaced in the past and it usually costs about $300 for the part and 1-2 hours labour. The repair took 5 3/4 hours according to them... $500 labour. Other places we called quoted 1.5-2 hours labour, with the longest being 3.5/4 hours. We got hosed, and would like to warn others about the shadiness of this garage.
