£110,000 was the base price + options (which really boiled down to Automatic, side exhausts, sport exhaust, upgraded stereo and quilted leather; there were also special paints and leathers).
As I have said before, the Hammond car set the bar lower than it should have been. If you notice the dealer sells predominantly Porsche product. As the Aeromax does not list in the guide books, the dealer will have worked out a rough value based on standard depreciation and also other cars for sale on the market. Given the low number of RHD cars and limited production run, I'd say he has under priced this example by £10,000. If it checks out, hasn't had any accident damage and is in excellent condition, I'd say this would be a very good buy for someone.
As Rich has said, it looks like the car owned by RPM, which was up at £110,000 until the Hammond car came on the market. I remember speaking to Russell at the time and he described the car as in like-new condition.
