You're well advised to obtain the drab grey international driving permit (costs aruond £7.00 from RAC and other places) which is valid for a year. I've never been asked for it by anyone, but some law enforcement agents might only recognise it and not your UK licence.

I assume you've done your research re. costings, but I personally wouldn't flip a car for 3 months. I would have thought that the all-inclusive rental prices with little risk, would be a more viable option than the hassle of finding, buying, insuring, maintaining and then reselling a car would be a non-starter (but I'm open to being educated ).

I have no idea why insuring with a foreign licence would be a problem - I've never found it to be so. Some insurers will load premiums, but others will not.

Dougie.
