New Brompton 12-Speed C Line on the way!

So after months of debating and saving (and - honestly - seeing if cheaper options made sense) I pulled the trigger on a 12 Speed C Line. I recently found myself needing to travel some additional distance for work, 3-4 miles throughout the day, in a place where I can’t really move my car once parked. I need to drive to the location initially, then bring the bike into my office (and several others)… So full sized bikes were out. I was looking at e-bikes, but all were much too heavy and bulky to easily move in and out of the office spaces I’ll be in. I found the Bromptons early on but was put off by the price. However, after months of trying to find alternatives that offered the same level of capability and portability, I was basically had no other choice since any competitor is frustratingly unavailable to purchase and doesn’t quite do the same job.

So, as a soon to be no owner, I was hoping to get some recommendations/guidance on things to look for/expect. I know there are some quirks with a bike this size, so any information you can provide on navigating those areas would be great. Appreciate the help!
