Posted on ATrustindex verifies that the original source of the review is Google. Honest guys that won't play you for a fool. Brought in a vehicle for a Pre Purchase Inspection from a dealer on Beach Blvd and was charged a reasonable price. Very grateful I brought it to Sully's as the vehicle wasn't even in a sellable condition. Also spoke with a long time customer outside the shop that had nothing but great things to say. I'd trust them with my own vehicles if I lived in the area.Posted on Cody BellTrustindex verifies that the original source of the review is Google. Honest mechanic who does great work in a timely manner. Continuously go out of my way to come back to Sully’sPosted on SeanColleen ManeseTrustindex verifies that the original source of the review is Google. THE BEST place to go to if you want honest, good price, no frills auto repair done. I used to go elsewhere and they would mess up my stuff and up charge me. I always feel comfortable going to sullys knowing my car will get fixed with no issues. They’re upfront, customer service is great. I never got upcharged here. Great people. This is my go to. I had a P0420 code and every place wanted to immediately change the catalytic converter. Over here at sullys we fixed my O2 sensor to check if it was giving that code and my check engine light went away. They actually listen and try to help you save money. Was able to fix my car for 1/10th of the price compared to other mechanics telling me to change my catalytic converter from the front and try to confuse me with other unnecessary stuff. I can’t recommend this place enough.Posted on James VlaisavichTrustindex verifies that the original source of the review is Google. THESE GUYS ARE HONEST... WHEN IN TO. MY ENGINE CHECKED OUT..
