If you want simple, easy to maintain, something you can spanner yourself and with good parts supply - you'll probably be looking at a British car from the 1960s. You don't mention how many people you need it for, but if it's high-days and holidays then an MGB or a Triumph Spitfire is a good starter classic. If you need a family vehicle, look at something like a Ford Anglia 105E. These would definitely be in the 6000 miles a year bracket. Of course, you won't get the mod cons you require, or the performance, and rust comes as standard. If you want something more modern, then you'll have more choice and the ability to cover more miles - but with ECUs and all manner of clever things fitted, you're unlikely to be able to keep it going on your driveway if you're new to fettling. These cars also come with intermittent electrical faults as standard which, believe me, you can spend a lot of time and money chasing. Even 'simple' cars from the 1980s can give you a headache. For example, their fuel injection systems can be difficult to fix when they go wrong. Something vaguely 'agricultural' (in the nicest possible way) would be a good bet, something like a Land Rover Defender or Discovery. These have great parts support and fantastic clubs but also - like any ageing vehicle - have build quality and reliability issues that you'll need to overcome.
