Just for the record, I've had bad luck with CPO advisors being responsive. I've been in contact with Mo (guy above), and he didn't seem to care for my business. Took two days to get an email from him with a couple of possible cars. I emailed him back asking for more details or other options and never heard back. Ditto for two more CPO advisors. "Kyle" from NorCal seemed very un-interested on the phone in helping me and said he would email me a few options (by the tone of his voice I suspected I'd never hear from him again.). He never once emailed me or called back. I talked to another advisor in NorCal, and basically the same deal. Interacted once and never bothered to call/reply after. They seemed to have no interest in selling me a car. Terrible follow up!
Since then I've decided to hold out for my M3, given the anticipated accelerated production schedule. So I haven't bothered to try and find another CPO advisor that was actually interested in selling me a car. Quite disappointed in the CPO experience.
