As everyone probably knows the BX was originally designed by Bertone, which we are all very thankful of!! However some of the design ideas were actually based on a prototype Bertone did for Volvo in the late 70s which used the mechanicals from the Volvo 343. It was called the Tundra and this is what it looked like:
This is quite interesting for me as I own both a BX and a 360 (the later evolution of the 343), so I've been trying to obtain some information about the designs. There's a bit on the Bertone website (where the above pic came from) but it's quite limited. In a recent American ebay spending spree I managed to get a copy of the original press release about the Tundra from Bertone's PR department which I was quite pleased about!! But other than that I cant find much else. So on the off-chance that someone has some literature of some sort on the original BX design or the Tundra itself that they wouldn't mind sharing please let me know!!
