The IMC GT was tough. I am getting ready to assemble what i think will be my most challenging build. The Tamiya McLaren MP4/4 WITH the Top Studio super detail set. At 1/20th scale my eyes will be a tad happier but if you've never seen this detail kit perhaps a quick Google will show you exactly what I'm up against. As far as a plain OOB kit, IMC and old Revell.
