ok well firstly, lookin at your age, and you are still young, and im guessin you are limited in money. so i would suggest a r32, only cause its cheaper.. It all depends on your budget, so let us know how much you wanna spend.. also what are you intentions in owning a skyline, like you want it only for drags, driftin, crusin etc etc??? U said you wanna know which drifts better.. I assume, stock vs stock, a r32..
If you wanna the difference between a r32 and r33, its been covered a billion times, so i suggest you search..
It all comes down to personal taste in the end and your budget..
hmm about insurance, best is to ask the companies.. would be same if u have a r32 or r33.. well also the fact if its a turbo or non-turbo..
hope that helps a little..
