As usual (but unusual for most repair shops), Clark's fixed what needed fixing and left everything that was working fine alone! We drive our cars until they get very old and eventually die, so there's always something that could break. So when it does break or starts to make unusual noises, Clark's either fixes it or evaluates it for repair. Their prices are the best we've come across in the 22 years we've lived in Florissant. I believe it's because they are honest and fair. Our lives have become much simpler since we found Clark's.
P.S. We are not related to anyone at Clark's and have no connection other than knowing them through their repair shop.
