I’m going to order a Performance MY today to replace my 2018 Performance M3. It’s hard to let the M3 go since it has nontransferable lifetime supercharging and connectivity, but it’s time for a change. Here’s my question… should I use my own referral code or my friend’s? Will I get all of the benefits of the referral, or just the $500 discount? My friend really wants me to use his code, and I don’t know if I’ll be losing anything by doing that.
