[twin plugged targa]

I was hoping there might have been more definative specs for RUF cars through the ages. Something that cars could be compared with for originality- if there is such a thing.
But it appears that the Ruf models do not have specific modifications and are personalised in their customisation, that they are perhaps the RGruppe of 911 Turbos!?
I dont have a problem with any of this, its just more difficult to try and put a value on something which has no comparison!

I have seen an ad for an '86 Ruf 930 which has low miles (less than 40K)
I am trying to get more specs, but in the meantime was trying to do my own background research.
Sometimes enthusiasts create their own personal websites with collected info.

Thanks for the feedback
