I used to have 2 dahons sold it too many problems in its frame joints because its made out of aluminum and the folding handlebar post a source of loosenes/noise/problems. got a bike friday it was ok didn't really fold so sold it. now I have several bromptons, the reliable raleigh twenty, and a moulton F 4 speed. resale value of bromptons is extremely high[in the USA] you won't find a used one in ebay[USA] or in craigslist i've been looking to get one for a friend over a year now. told him to just buy new as prices go up $100 every year[USA] [because of the falling $] so if you wait it will just keep going up.
enjoy life now don't postpone it the economy will crash and the dollar worthless but at least you can still ride the bike for FREE !!
