Until the middle of last year I had run a 260 then a 385 as daily drivers for more than 6 years and a combined c.190,000 miles (On LPG thankfully). I did most of my own basic servicing and unless you get a car with a particular issue to deal with it shouldn't prove to be too expensive to run. The big issue is that they are now all at least 10 years old and some parts are getting harder to get a hold of. The upside to that is this club which have a number of resourceful members who put a huge amount of effort to sourcing (and in some cases arranging the fabrication) of replacements.

I only stopped using mine daily for a combination of it being too nice a car too keep banging the miles onto and my work commitments was preventing me spending the necessary time on maintaining it as I would like. But it's such a satisfying car to drive and the membership on here are a fantastic bunch who will be able to help you with just about any issues that arise.
