Hi Lukas, it is amazing what one can see in an Asian country and I would imagine that Cambodia would be no different. The cloth or vinyl tops were a fashion statement in the seventies, and even the Humber Super Snipe, finished up with a vinyl top when they manufactured the Humber-Chrysler Imperial - but like with so many things British at the time, that car couldn't prevent the Humber Company from going under. More so's the pity as they produced some lovely cars - think back to the Hillman Minx (lovely car), the little Humber Vogue, the Sumbeam Rapier - yeah, not bad.
Even I had a Humber Vogue I bought for $120.00 and, apart from a new radiator, did not have to spend a cent on the car for a full twelve months of constant use, and then sold it for $180.00. Big business ! Regards Styria
