Possibly (probably) just an idle fancy really.
However, I really like this era of Porsche - it's (for me) when the design was at its most coherent - small, light, simple.
The later versions got bigger and heavier, and whilst I like the red-braces era blistered arches/whale-tail/sniffing the white lines off the tarmac style of the Turbo etc they're just too over the top for me.
The 912 has a 1.6 litre boxer 4, it's got very little power - about 25% of what my Volvo estate has, and that's the appeal in some ways, it's a car that you'd have to drive with a great degree of delicacy to make good progress, rather than relying on the AP's to get rid of speed and then then hard into boost to regain it.
I don't have a spare 20k kicking around, so it's pretty much academic really.
