I can't lay claim to these models - they're stuff I got online . . .  

I felt obliged to so liveries and make renders - really interesting for me to seeing these two side by side and compare the differences . . . 

'67-'71 is just a few short years, and yet the game clearly moved on on leaps and bounds during this period - a technological arms-race.

Whilst the P4 isn't without its obvious charms, for me the 512M is always gonna be The Daddy. 

I grew up in a household where LeMans was on loop 'til the VHS tape broke . .  and OK, it was an S in that film, but I quickly got hooked on the high backed, boxier lines of the M.

If anyone out there has got a shedloads of cash and wants some help to put a new spin on the 512 - you know where I am. (along with just about every other red blooded Designer on the planet!)
