I can confirm that I was contacted about the car last week, and through my dealings with the Dean/Dave combo, I was advised that Martin Grigg did the compliance on the car. A blue Lancer coupe was found at a wrecker, and the VIN plate was purchased for that car. The Evo 2 RS was separated in Japan (the driveline was pulled off the chassis), and the car was sent to Australia in two separate shipments per the laws at the time. Once both shipments arrived in Australia, Martin Grigg bolted it all back together. Perhaps the owner had the wool pulled over his eyes and was unaware that the driveline was actually from a different (non RS) car, hence the air-con inclusion. Whatever the case, it's definitely a re-birth and certainly not eligible for rego in NSW.
You could option an RS with aircon. If someone who has access to the CAPS system has time, they could type in the original VIN and see what it says about the car.
