I did and I didn't regret it for a second, it sees tons of use and is pretty much indestructible. The design is timeless and the second hand market for Bromptons is pretty good, they hold their value better than any car I've ever owned. The first five minutes require some care but after that it's super stable and very low on maintenance given the complexity of the folding. It's small enough that it fits the cargo space in my car where it normally lives so that I always have a bike with me wherever I go.
If there is a downside that would be that even though the wheels are quite a bit bigger than the ones of the bike showcased here that the tires are very high pressure and need frequent topping up.
