Oddly enough someone at BMC must have like the four-headlamp arrangement because the ungainly Austin 3-litre saloon shared it.
The 3-litre was an interesing old bus, though, being a RWD, hydrolastically sprung, RWD saloon derived from Issigonis' FWD 1800. It featured self-levelling rear suspension and its ride/handling was reputedly excellent. The 3-litre's engine was a seven-main bearing variant of the Healey's C-series which was also used to little effect in the MGC.
You've probably guessed that I'm a Brit (because I've written 'saloon' and not 'sedan') and in my younger years (I'm 38, BTW) it always filled me with patriotic pride watching US films and TV programmes set in New York because taxi drivers there drove Austin 3-litres. It was only much later that I learned the truth. Only BMC could have managed to build a luxury saloon that looked like the Checker taxi, and what's even stranger is that the big Austin was meant to form the basis for a junior Rolls-Royce, or Bentley...
