Ok, this is giving me a nose bleed...
IF you can even entertain the thought of purchasing an R35, that why the fuck would you waste your time and money buying an R33, just to sell it (and loose plenty of dollars) in, say, a year or 2 time, then buy an R34??
JUST BUY AN R34!
It is so obvious that you are new to modified cars. You do not NEED to buy a modified skyline as your first one. Buy a stock one, they are still great fun and shit on many cars. I enjoyed my first skyline in stock trim for over a year until I started modding it. It gives you a great chance to get to know your car, and not get behind the wheel of a car you may not be ready for.
So my advice is..
Search around for a nice STOCK R34, and start from there. you will get one for just a wee bit more than an R33 anyway.
Learn in it. have fun in it. enjoy paying heaps to insure it. THEN, IF you want to spend some money to mod it, go for it, OR just sell it for the $12k you bought it for, and with the $100k you have in that shoebox under your bed, go buy your R35 ya muppet.
