For me, it would be this Remington 760 in .35 Remington that I just recently picked up, been looking for a pristine one for years, and I don't think this one has ever been fired. 1979 vintage according to Remington. I have a 760 carbine in 30-06 that can do everything this one can do, and probably even better, but a 760 in .35 Remington is simply the epitome of coolness as far as I am concerned.
The other one I'd buy just for the hell of it if I could find one in pristine condition would be a Remington 600 with the laminated stock and ventilated rib in 350 Remington Magnum, even though I don't have any kind of need for it.
