mate my advice is just use common sense. you have to remember that although we are all skyline enthusiasts, they are still a 15-20 year old jap sports car, not a nasa rocket. just dont be a wanker, warm it up before you drive, always service it when due, dont drive it like you stole it, and let it cool down a bit before you turn it off. ive owned skylines for the last 9 years and although they are a good car, youy dont need to baby them too much. just treat it with respect, like you would any car.
