Why Test Only matters
A check engine light is a problem to solve, not a sales opportunity. We read the results. We don't sell the fix.
No repair shop. No reason to fail you.
Test Only
A Test Only station is licensed to test, not fix. We don’t sell parts or repairs, so there’s no upsell waiting on the other side of your results. You get an unbiased test and a straight answer.
STAR Certified
The state holds STAR stations to tougher performance standards, and only STAR stations can certify directed vehicles, including ones flagged as gross polluters. If your DMV notice says “STAR station required,” you’re in the right place.
