Battery hire is available for £30 if you choose 1500 miles pa on a 3 year contract, see:
I have driven with and without doors and then bought with doors as I preferred it. They give little protection from the weather, but make you feel a bit more secure and give the added advantage of making the floor either side of the driver’s seat a useful place to carry a weeks shopping, dogs, etc which is impossible without doors, plus people are less likely to climb in with doors closed-they can turn on your hazards and sidelights and flatten the battery.
Long front mudflaps are essential, doors or not, the Renault windows are absolutely terrible and spoil the whole thing.
Doors cannot be retro fitted and doorless models are much harder to resell, so I’d definitely choose doors.
The downsides are they need constant catch and guide adjustment to stop them from rattling, plus the clear plastic bases scratch very easily.
Transit with long ramps easy enough, as is moving on a lawnmower trailer.
Good luck. Keep your eyes open on here and on ebay and AutoTrader-if you keep looking a bargain will surface. Don’t worry about where it is, many people can move them cheaply enough, or you could drive it over carefully planned days and make a holiday of it.
