While there are many review sites customers can use when researching a company, few are legitimate enough that you can count on the information.  Often “review sites” can be altered by the staff of the company writing great reviews about them or competitors writing horrible reviews about them.  However, sites like the Better Business Bureau give consumers an option to see verified complaints from other consumers.  While they will not see any glowing reviews about the car transport company, the lack of complaints or volume in some cases, will give you an idea of what your experience will be like.  You can search companies under the “check out a business or charity” section of the website and search by company name, phone number, web address among other options.
