mc5 - Riddle-me-ree Crescent

Collective consciousness riddle-making. The answer must be a London Underground station name.

My third is quite GAMIN and not so ADULTE

I'd better be WARY so not to cause FAULT

My fifth is in GOUACHE but nowhere in OILS

My sixth duels with SABRES but never with FOILS

My seventh's ECLECTIC, PRETENTIOUS as well

My eighth is a BUYER with nothing to SELL

My ninth is in CORAL but nowhere near REEF
