[QUOTE=mlau;21140024]I just picked up my 2007 Brompton from the local bike shop.
They'd quoted me about $600 in repairs...which I sucked up and paid for.
Then, they told me that I'd need an additional $1000 for new problems that they found (rear wheel damages, rear cog not working, replace rear hinge).

Agreed that it's time to do at least some of your own repairs. For $1000 you could buy every Park Tool you'd ever need, a nice work stand, and have some $$ left over. And, if it's possible to do, somebody(s) has a youtube video showing you how. The Park Tool website has many excellent repair videos. 'Calvin'at Park Tool is THE MAN!
Good luck.
