Phil, prices seem to vary quite greatly on the S1 and dealer or private sale, colour, mileage and condition all seem to be factors that effect price. Lowest I've seen in the past 12 months was low £30,000 and the highest £40,000.
It is quite a wide spread but anyone who looks at a few S1s will soon seen the variation in quality and reason for pricing.
The car at Techniques should be a good one (I don't know it, so may be incorrect); however, they do know how to prepare a Morgan.
The C4 OGS car looks familiar and may be owned by someone on this site but I cannot recall exactly why I know it.
The black car is unknown to me and this site.
