VIN doesn't contain any info other than make, year, and model type (2 dr ht for example) and assembly plant as well as the sequential number.
Options are recorded on the trim tag on the cowl (thought not all of them, only the few that the stenographer felt like typing). So if she was tired and in bad mood mood you might get two or three options; if she was happy and ready to work you might get every option on the car recorded from group one down to group five.
Dealer wasn't recorded anywhere except the shipping tag (part of the paper work in the glove box). All of this was trashed by the used car reseller to keep you from contacting the previous owner to find out why you sold the car when the original owner traded it in.
