I'd say the Fujimi enthusiast kits. I remember the Porsche 356 being a stunning kit. Complicated little bugger, but outstandingly detailed. Look at some of the Mobius kits, the Galaxie Chevys and the really detailed Tamiyas and Hasegawas as well. No one can guarantee 100% accuracy unless you can actually start it, but these things are relative anyway. Make them as detailed and accurate as you like.
