Wheels May 1991:
Best Hndling supercars - BMW M5, Ferrari 348, Honda NSX, R32 GTR and Porsche Carrera 4.
In the same issue there is also a 6 page road test of the R32 GTR, they have it as the first local drive.
I was lucky enough to be able to buy this issue in great condition at a swap meet couple of weeks ago for $2!
Another good article on buying a used r32 gtr is in 'Unique Cars' June 2003 issue.
I also picked up a book a month or two ago called 'Nissan Skyline GTR' it is a Brooklands Road test book and has the major road tests articles on 32, 33 and 34 gtr's from 1989 - 2002 (included is the wheels road test of the r32) but all the pictures are in black and white.
