I bought mine from Sytner, and use them as they are the only nearby BMW garage.
I had a couple of issues once I bought the car, and had a slightly disappointing experience with the salesperson. Once the sale was completed without my service book being recovered (despite it being an AUC), I struggled to get any timely response. Once i escalated to the business manager within 2 hours got 2 calls, one from the business manager and one from his used cars manager apologising and offering solutions which included getting his courtesy car for the day (I also asked them to take a look at an issue), and changing the inner roof for free despite it being a cosmetic issue not covered by warranty.
it took them a few months to finally find the issue and sort it out, but that was because it wasn’t happening every time and to be fair they did change most engine components so can’t complaint overall.
