Didn’t take a lot to guess as I’ve dealt with Ken before. He’s a straightforward chap, seems honest and happy to rectify any issues that come up. His cars seem genuine enough. My strong advice however would be to get someone who knows these cars well to inspect it. He could have missed something that you have to live with or rectify further down the road and although it might seem hassle now, the investment in getting it inspected means your fully aware of the likely future issues (if any). Looks like a good car to me (as all his cars do) but also do a detailed check of the service history with your own eyes to validate a good MD/specialist Indie maintenance record.
These cars are pretty robust in my view and with that mileage if it’s been well maintained it’s only things like subframe and general corrosion that I personally would worry about. Worth making sure there is decent life in tyres, brake disks and pads or factor in the replacement into your budget as they cost a few quid (although knowing Ken these will have been attended to if too far gone).
Or just buy it and have a massive grin on your face as you drive away!
