Has anyone ever seen this kit in person or seen detailed photos of it?
Is it any good?
What exactly do the 'grade-up' parts include?

TIA, Matt

I have the 1/43rd version. It has photo-etched radiators and seatbelt parts and white metal radiator pipes. A metal engine/transaxle, photo-etched suspension parts and a metal monocoque. A big piece of foil for the engine bay heat shielding is included.
