Gti-6's ROCK!, all cars need attetion and service, with a gti-6 look after it and it will serve you damm well.
Really though, i think the following probs are petty at worst.
A few members here have mentioned that the gti-6 exhaust/baffles can work loose, rattle and be a right pain. This has come from a few drivers.
Here on AF, ive also heard of the Battery being killed, mainly due to heat in the engine bay, but this also happens to S16's.
Uneven pad wear is common and the disks are easy to score/damage too, but this seem sorta common across the 306 range. Mind you pugs also get driven in very spirited manners sometimes, which would happen to most regular cars if driven so.
A few service centers mention that Coils go to, owning a S16 you would know of this too. Also Clutch cable problems, with the feel of it and action, being a regular complaint.
Perhaps also engine mounts, drive shafts when driven like a daft thief, and serpentine belts, don't forget about the timing-belt too, every 80,000 just like all 306's to be on the safe side.
Paint quality isn't the greatest, and 306's seem to scratch real easy.
Having said all that, the actual engine is pretty well much bullet proof, and a standard and serviced car will serve you well, stockVsstock, i think the GTi-6 is King in the entire Pug hatch range. - chris
ps, this is a logical upgrade, but if money stretches consider a Clio Sport too. Its not a pug but im sure you wont hold that against it
