Auto Repair Shop in Valley Park, MO

What Sets Us Apart

Benchmark Complete Auto is not your average auto shop. We are proud to be a family-owned business with a friendly atmosphere, and we are also proud to treat our customers like part of the family. This is how we have operated since we first started serving the Valley Park area in 2004.

Auto Repairs We Do

When we say complete, we mean complete. We do all minor and major repairs for all vehicles, foreign and domestic. The repairs we can perform include, but are not limited to: air filter replacement, air conditioner services, electrical work, driveline service, power steering flush, fuel/air induction clean-up, cooling system service, transmission service, axle replacement, clutch repair, battery replacement, oil changes, and oil filter services, wheel alignments, tire pressure, computer diagnostics, brake systems, exhaust systems, radiator services, power steering work, light replacement, suspension work, and fuel injections.

We also perform preventative maintenance work. As a car owner, you should know that it’s important to maintain your car’s health and functionality by completing preventative maintenance tasks within a certain period. For example, tire rotations are a good idea every six months or 6,000 to 8,000 miles. Your wheels should be balanced and aligned every six months or 6,000 miles. At Benchmark Complete Auto, our certified mechanics will perform any of these services. We can replace your car’s spark plugs, clean and test your battery, change your filters, or do anything else your car needs.

Signs You Need Auto Repair

When you’re sick, you tend to get a runny nose, a headache, fatigue, and maybe even a fever. But how can you tell if your car needs repairs? In general, if your car is making an odd sound or emanating a strange smell, you will want to bring it in to be inspected and repaired by an expert. These symptoms are easily noticeable and can mean that your car requires any number of things, from minor repairs to major ones, so don’t ignore the signs if you notice them!

Sometimes, your car will tell you if it’s having an issue. If you notice any strange lights turning on on your dashboard, it’s time to bring your car in to be checked out. Modern vehicles have a very sophisticated and smart computer that can generally tell you what’s wrong, pointing you in the right direction for repairs. For any auto repair for any vehicle, be sure to bring your car in to see the experts at Benchmark Complete Auto in Valley Park, MO.
