Peter,
You are correct that brothers Mike and Gordon Spiteri now run the garage, but John Day is still very much an active part of their setup. They have performed a significant overhaul on my Fulvia over 2019/20, and I chose them in part because of the locality to my preferred bodyshop, John Day's reputation & professional opinion, but also Gordon's enthusiasm for old Lancia and his commitment to getting the job done right. As for value for money, you make your own decisions, but they are on a par with my Fiat Dino specialist and cheaper than my BMW specialist; all based in a similar part of the UK for similar garages.
Overall, I've been very happy with their work and would recommend.
Andy
