I know the car, standing at Eporsch for ages. They might not budge a lot in price but it has been there since summer last year IIRC.
Also tested by Jeremy Clarkson in 1996 IIRC.

Now, to make it road legal in the LHD country you ought to convert the headlamps to LHD as well as having a rear fog light the other side. (UK is right)
But: two things. Ruf came either as build at Ruf in Pfaffenhausen, and then it comes with a Ruf VIN. Alternatively it could have been converted by the now defunct Ruf dealership at Weybridge, Surrey. All the mechanics were incorporated by GT one at Chertsey; give them a call or do a bit of research: pretty sure they might remember the car.
You could always contact Mark Bongers at Ruf in Pfaffenhausen for further information or the build sheet. By the by, all papers at Ruf UK were lost following the move.
Peter Morgan is good, but ...
On the subject of Peter Morgan: I
personally feel that his report is a good beginning but it doesn't tell a complete story.
If I were to buy a specialist 911 and a RUF in particular, I'd want someone who:
1.Can assess what is period to that particular RUF and what not (e.g. factory delivered with some lightweight options but a standard bumper at the back)
2. Can assess what is original to that particular car and what has been replaced with reproduction parts (wings, bootlid, front windscreen, what serial number and build date are on the Fuchs? 16 inch Turbo wheels from 1986 or a set dated correctly from say 07/1989- although this one is equipped with the speedlines)
3. Can assess the quality of a restauration. An Ruf was a fast car and a good number of them have been wrapped around trees. Have a look at the floor of some the RS's and you can sometimes see scars which were left as a reminder. A talented bodyshop man spots these things in a split second. Peter is not a bodyshop man. Also, what is the paint thickness. Porsche had 120 microns. Any quality restauration would want to emulate that as close as possible, unless the shell has been e-coated: that adds a few microns. Peter does not test this IIRC.
4. Can assess the state of the internal bit: engine, gearbox, suspension, brakes, Turbo etc. Once again, I'd expect a compression test AND an assessment by a specialist such as Bob Watson, Fran Tuthill, Neil Bainbridge, Mike Bainbridge, Crispin Manners at Oak Tree, Jaz at Carrera Performance, Garry at Autofarm etc.
Mike Bainbridge spotted in 2 minutes items that were not quite as porsche intended on my engine when I broke down with the car. Needless to say: its a waste of time and money bothering with anyone who can't do that. It is even more important to do that if 6 figures are at stake.
Peter Morgan's comprehensive reports are good and I do appreciate what the man does BUT my personal feeling is that this is merely "a good start" to get a feeling of the car.
*Edit* This is based on a number of £350 reports I have seen from Peter Morgan for more "common 911" cars. It might be different for a RUF report.
John Ward at Autofarm knows a bit about the BTR so you might want to fly off an email to him with my compliments.
(goooooddam, is the Belgian mentioning my name again
)
Good luck in your hunt,
Bert
.. only a few insurance compagnies make an exeption and will also insure younger cars on tax.value 
lijkt me sterk dat Ruf bij RDW wordt ingeschreven bij je Kentekenbewijs , maar goed kan t mis hebben
..i havent decided yet... cant wait 
any interesting things coming out of the ppi by Morgan?
