From what I have read, the Bis version was supposed to be better than the aircooled versions. It may look the same as the aircooled (the aircooled version itself went through a series of modifications/improvements as well through the years) but there has been a lot of improvments under the skin. It should be quieter, smoother (because it has bigger tires), synchromesh transmission, a hatchback, intermittent wipers, rear wipers, electronic wash/wipe, heated rear windows, new 704cc engine therefore marginally faster, widespread use of galvanised steel (from 1989 onwards), it was full of kit (at the time) - just to name a few. It is one of those cars, I think that needs to be regularly serviced (on time) by Fiat or a specialist from new. Any deviation from the service routine meant potential future reliability problems. There are some overheating issues (although I have yet to experience this) but there is more than sufficient threads in the forum that would resolve or minimise this risk.
