This is going to be about the best I can do for you.
Go here...

Click on "Nissan Skyline"
Next you'll get re-directed to a page with a "map" of Japan where you select the region.
Click on "All Country"
Next comes the tedious part.
Narrow your search to the following criteria.
Car/Grade Name Nissan Skyline GT-R(It's about halfway down the scroll menu)
Next, select your years with the "Age Type" menu
Select H7 (1995) to H10 (1998)
After that, click "Narrow by this condition" and it will now list only base grade GT-Rs for your viewing pleasure.
Pricing is in yen of course, but you can use
http://www.xe.com to get your monetary conversion done.
But, that price most likely won't reflect the actual price of the car in the U.S. as it was never sold there, so I don't know if a bank will give you a loan on something like that.
Good luck, and be sure to get copies of all the MotorEx paperwork before you purchase the car and have a lawyer go over it to make sure it's legitimate.
