Finding a reputable shop requires researching the area using websites such as Angieslist.com or BBB.com to help compare reviews and complaints of each place. These websites sort each repair shop based on its popularity among its consumers. Although researching can locate local shops, be sure each mechanic is certified by an ASE certification to avoid any competence issues.
Angielist.com organizes shops based on the services they offer. While using these review sites, make sure to use the proper keywords to help locate specialists that are able to work on gas tanks and have the knowledge and experience to replace them.
After finding a shop, focus on researching the mechanics that work there. Begin researching each mechanic to see if he has any particular certifications. Organizations, such as the ASA, act as networks for honest mechanics.
Also make sure to use community forums that have access to the same type of vehicle. These forums can often help in finding a local shop that is trusted among the community and that is capable of servicing and repairing gas tanks for a vehicle. Cross referencing those found through the community forums with Angielists.com and the Better Business Bureau should quickly narrow down the results.
