Re OYT - this is now getting rather tangled - are we sure it's not Russian hackers sabotaging the data?
More seriously, lets strip it back to the known facts.
We have two pictures (confirmed) of OYT at Lilford Hall in 1988 (thanks Jeff)
Moving on to 1993 the car is pictured (with numberplate visible) participating in a rally (plaque visible on bonnet) on the back cover of Slice 132 (Picture not posted here due to Slice copyright). Caption reads "Hear the leather, smell the sound. Phil Mickleson's tidy V8 Coupe" (the photo was by John Gaisford. )
Then we have a photograph posted by yourself described as 1994, showing the car at Curborough: As far as I'm aware, this is the last picture of the car roadworthy until the present day?
Then we have the entry on V8 Church here
As can be seen from the text, it's undated, but clearly after the above, as it makes reference to them. Clearly by the description, it was in need of restoration at that point. The accompanying photographs are unmistakable (note back on the posh wheels!)
At some point after this, the car appeared for sale on Car & Classic. The ad is undated. Note that the current owner, in Jeff's slice article, says "he has owned it for the last few years, and done a lot of work to get it back into shape" - how many is a few? 2, 3, 4? So if the ad was from when he bought it, it might be, say 2014, or 2015? We don't currently know exactly, but it's not particularly mysterious?
Here's the car as currently photographed by Jeff last summer (thanks Jeff). As stated above, the current owner has done extensive restoration, which may well inclde the more tasteful interior colour.
Yes, it is unequivocally on the road then, but note that its MOT history only contains one MOT pass in 2017 - entirely consistent with a car that has been off the road for a long while and only recently (Oct 2017) completed a restoration :
