I bought a 2007 CPO 328i and it came with a spec. sheet listing all the items and options that it came with by price including the total MSRP it sold for when new. Just ask the dealer it came from originally to look up the spec. sheet from its VIN # and give you a copy.How can one find out what features came with the building of a used BWM. Like if it came with alarm, CA, or any other request when it was build or even after and may have been added on by a dealer, thanks.
