Id personally go for the mk2 st mate,
Well im torn between a mk1 Focus RS, a mk2 focus ST (similar price range) or whether to go all out and get the new focus ST2 on finance :/ decisions decisions lol. I definatly want something with alot more power though. Ive made aload of visual mods on my mk6 but its only a 1.3 LX so there isn't much point doing any perormance mods. Its been the first car ive ever done any mods to and IMO i think it looks pretty decent but theres just no ooomph when driving it lol
Better chassie and more mods than the mk1 RS
Duplex exhaust as standard too and an easy upgrade to mk2.5 body styling if you ever decided to.
