I've done business with Christian Brothers in Frisco on three separate occasions. Each time the staff has been courteous, forthright, and helpful. As opposed to trying to "up sell", they identify items needing attention and then help prioritize which items should be addressed first. They've even gone so far as to explain which repairs could be done by the do-it-yourself mechanic in order to help keep down costs. When repair quotes were higher than dealership estimates, they took the time to explain their procedures, the advantages over standard maintenance, and why they commanded the premium price.
Christian Brothers addressed the requested repairs in a timely manner. Their free shuttle service is quite helpful and they offer beverages for those who would rather wait in their lobby while work is being completed. We'll be back when future needs arise and I'll gladly recommend them to others needing service as well.
