I dont think its petrol prices, its just that they have now just begun to go from old banger status to classic, and people are jumping on the bandwagon. As an economical runabout it doesnt make sense, because the maintanaince is high, and comfort low! A Panda can be just as economical or a Cinquecento without the rot problems too! I think people have been interested recently down to ebay mainly, as prices being fetched are higher than normal, especially for the BIS, and yes down to the club in some part. I would guess eventually that all these newly found BIS cars will dissapear in a couple of years, mechanical failiure and rust will see to that on the uncared for cars. It happened with the aircooleds about 6 years ago, then there were still loads about and all of a sudden they vanished. Now, most aircooleds are cherished cars, not runabouts like a lot of BIS cars. Hopefully with the club the surviving BIS will be loved and looked after for a long time as historically its Fiats last rear engined car and reliability aside a great concept.
