My last car was a 156 V6, cracking car, and I appeared to get lucky, as had virtually no problems in 3 years of owbership (save for a brake servo failure after about 3 months of ownership). I also got lucky living only a couple of miles from SGT in Taplow, where the service seems to be a mile away from most Alfa dealers. That said, I would be wary of buying a secondhand one without getting it thoroughly checked over, and look out for the 72.000 mile service ! On the V6 thats when they change the cam belts, and its very expensive (was a company car, but the invoice was the wrong side of £1500).
