Been using Suburbia for 55 years; Mom & Dad used them before that. I've never neglected to replace a timing belt on a car with an interference engine, but it can be a serious problem. Joe or Mike, or their Dad Bob before them, always told us when things needed attention before they caused catastrophic failures. These days, with cars that go for 100,000 miles without needing anything but tires and batteries, we mostly use Suburbia for state inspection and emissions testing. I'm going to be disappointed of the two brothers close their business before I stop driving; I'd hate to go anywhere else.
