First up: Monogram's excellent Mazda RX7 kit. It's better than Tamiya's. Has full detail, and is unique in that it's a base model car w/alloys. Fun, easy kit to build and detail. I built this about 6 years ago, I built two of them identically. A client wanted a model built of this exact car, what I did was build two of them at the same time, because I wanted one too. Saved time, and no regrets over giving a car away, regardless of being paid for it.
Second up: 1986 Mazda RX7 Turbo
This is a semi-restored kit. I started out w/my original Tamiya RX7 that I painted in gold and used aftermarket gold BBS rims on, and robbed it of it's interior, rear glass, engine, and taillights. I then took a fresh kit, added Integra front spoilers (customized front and stock rear for the rear skirt), and some custom side skirts from a Q45 kit. Covered w/Tamiya pure white, and wheels are Hoppin' Hydro's Belaggio's.
