Thanks for help folks! In regards to the one you mentioned SPPR,
https://www.truecar.com/used-cars-fo...5/2015-bmw-i8/, this is a branded title/lemon buyback, per the carfax report i pulled. I have seen a few of these around at that price point and all have been branded cars. which could explain the price difference. Granted you can get a good "deal" on these types of titles, professionals often recommend against it. Depends on your risk tolerance i suppose.
