1. You dont. It is like any other wagon.
2. Normal for Skyline, pod, zaust, cooler, fuel system, high flow turbo..... and the list goes on.
3. Airbags? Seriously I wouldnt have a clue.
4. Same as Skyline, 7psi. If you read around somepeople reckon 14 psi (1bar) and some people dont. I ran my old r33 on 12psi most happily for about a year with no problems, depends on how hard a life it has had before you took ownership I guess.....?
5. Dont know sorry, SK is prolly most qualified to answer that
6. First night I bought my stagea went out cruising and for some unknown reason we ended up in a known defect station area, and wouldnt you know it we were locked in and they were defecting the crap out of all the cars exiting the carpark. When it was my turn the officer asked me what type of car was it, I replied, "It's a volvo 850S." so he told me to go on my way Just lucky I guess.
But still if you are doing something stupid in any car, I would expect to be reamed by the police.
Oh and Welcome to your new aDdIcTiOn
