FAQ

What should I take with me?

The registration or the renewal notice, and the keys to everything on the car including the locking wheel nut key. Turn up with a warmed-up engine and enough fuel in the tank. If the battery was disconnected recently, say so, because that alone can end the visit.

What fails cars most often?

Warning lights and readiness monitors lead the list, and behind them sit oxygen sensors, catalytic converters, evaporative system leaks and a gas cap that no longer seals. A loose or cracked gas cap is the cheapest failure there is and one of the most common. Tighten it and drive a few days before the test.

Is a cheap test worth driving further for?

Rarely. The test is the small number in this equation and the repairs are the large one, so what matters is whether you trust the place that reads the result. Convenience counts too, since a failure means coming back. Pick somewhere you can reach again on a workday.
