My favorites are the Monogram Exotics from the 70s. They made the Porsche 911 and 924, Datsun 260Z, Mercedes Benz 450SL, Ferrari 308 and others. Great curbside kits for the beginner and fun kits for the advanced modeler to relax with. I actually emailed Revell a couple years ago and got a fantastic response from the guy who designed them. They are mostly out of production, but the 911 shows up occasionally on the release lists.
