Actually it is important to remember that they are very simple cars - most work on them can be done by any competent mechanic or indeed by yourself if you have a reasonable level of DIY skill (much more common in Antipodeans than Brits in my experience!). The only computer diagnostics are accessed via a standard Ford OBDII port, any garage can do this, it's nothing like the complexity of a modern BMW such as your other car. For some of the other things that need "adjustment" like body fittings, trim, etc they are very much in the classic car tradition and any classic car specialist would feel right at home. Also the matierals used are pretty much corrosion-free (though perhaps you should watch out for termites?).
My only concern might be overheating in very hot conditions, and sunburn.
