Boy, if you love old Porsches and have unlimited funds, what an auction this would be...
No way to decide between this bunch, you'd just have to buy all eight. At the very least the '67 R, the '71 ST and the '72 RS prototype (presumably the orange car, it has a 1972 oil flap). Load them all in the transporter, and then drive the '97 Turbo S back home. That's what I'd call a good weekend...
