Oh, I didn't realize you could even buy them direct now. I was looking at >~£1200 in shops or ~£1400 for the models in stock where I got mine. (The cheapest used to be single speed, and 3-speed is stretching it for non-trivial hills like the scarp round here.)
Half the price of a Kwiggle [1]. Seems like a bargain to me.
[1] Comparing apples to apples, the base Brompton is a 3-speed for 850 euros. The 3-speed Kwiggle is 1690.
