I have an MG TF which I think is running a bit hot, but the temperature guage that comes as standard on them is ****. How hard would it be to wire up a digital guage?
I'm not by any means a novice but I've never done this sort of wiring before...
Talk to Rimmer Bothers, MG Club or Brown and Gammon in Baldock, both should be able to sell you a kit with the gauge, sender, necessary plumbing adjustment etc.
