Brakes or brake pads
Cables and cable housings
Tires,
Chain
This can start adding up quickly and if it reaches the $800-$900 range, you probably can get a newer used bike. I may pay that price if there's no work involved and the cosmetics were in great condition, but only $300-$$400 if it needs a lot of work.
I think the price is fair when when you consider that the price was 600 less the amount to get it in proper working order. All the things you listed are included in the purchase price. Also, I've noticed with Bromptons and other bikes of similar desirability the original cost of the bike is kind of irrelevant. There are more people wanted used Brommies than there are used Brommie's -- Especially in and around NYC. I'm sure if the OP doesn't buy the bike at that price, the seller won't have too much trouble finding someone who will.
Having said that, I still think a newer bike is the safer choice in this case.
