School me on B-series wagons...

Shufflin and I will be looking into purchasing a B-series wagon in the next couple of months, all things going to plan.
Can all you late model gurus give us an idea of what trim levels they came in, common things that break that are expensive or cheap to fix, little options that people may have added that add value etc. What's the go with the ICC? Only available in pov pack LCD version?
Not interested in LPG at all so it will have to be straight petrol cars.
I assume the rear doors and rear seat bases are the same between sedan and wagon, so if we were to come across an XR6 interior or similar everything would swap straight over bar the rear seat back?
