Nice of your dealership to do that. I get a free cup of coffee when I visit my BMW store.
Well, I used to. Now with Covid, there is no free food.
Laguna is one of my bucket list tracks, but as I am on the east coast, it's likely not going to happen unless I borrow a friend's car (Miata) or rent something, mostly likely a Miata. I'm not a big Miata fan, although they are fun to drive, if you don't mind a car motivated by a squirrel.
If you get/got the track bug, which is a bug worth having, you need to do a real HPDE school with the BMW CCA or PCA or Audi or any decent club that has in-car instruction as well as real classroom instruction. That will help you learn the line, car control concepts, and proper braking. It will take years and years of instruction, and after you have spent most of your childrens' college funds and your retirement, you may feel like you are finally "getting it".
Worth it.
Congrats on the lovely car, mine is a twin. Albeit with 2WD and three pedals.
