I saw a post that outlined exactly how to find which version you are using. If your Taurus SHO bcomes Mark Martin's Valvoline #6 car, then you have version 1.0 for sure. If the car wash says it's only 50 crites (and not 5000), then it's 1.1. If the Muscle car license tests actually take anything other than I-A, then it's 1.2 version.
Or you can try different versions of the money code/"a ton of cash" to easily find which version it is. My site only has 1.0 codes, but the basecodes for hybrids are for different versions. Beware of some other sites, they may only tell you codes for 1.0, or they may be fake codes. Find good ones that tell you different versions.
