Heres what Erik told me about the Santana MPV.
Erik said:The SH 7181 was a MPV built by the Shanghai Auto Research Institute on the platform of the Santana, to commerate the 40 years anniversery of the People's Republic in 1989.
It was a unique design, as VW itself made its first MPV (Sharan) in 1995.
The car was named SVW 7181, but VW protested against the use of the SVW designation, which was changed than by the Chinese into SH, and VW protested against the illegal use of the Santana platform.
There was only one prototype, I have never seen it (they told me several times that it was in repair) but they gave me some pictures. The question of the use of the Santana platform was very important, as Shanghai now had to buy Rover platforms, not allowed to use the Santana's.
