It was on here for £12000 which in my opinion is about right, even if the dealer paid the list price he's making not far short of £8000 on it at that price.
I actually viewed it in Apr 2015 when the previous owner first wanted to sell it (later on he removed it from sale, ran it last year on track and then re-advertised it a couple of months back. My impression was of a car that wasn't especially well built and really needed money spending on the suspension and braking setup and a good tidy of the electrics (and as someone on here noted, as new speedo, it's stuck at 30mph!). However (and please bear in mind my Rover V8 knowledge is not extensive) the drivetrain itself was pretty spectacular and had had a lot of money spent on engine, gearbox and diff. It went very well and sounded fabulous. For me it's a car for someone mechanically competent to buy for circa £11000 and then spend another few thousand and a lot of time on. At that point it could be a pretty special car.
