Bagdad !
No question.
Good weather. Cheap petrol. Plenty of international visitors to converse with. Lots of vintage motor cars to take an interest in. Most importantly lots of aviation. Plenty of military aircraft flying around all the time and lots of great airshows. In fact there is one on as I write.
Yes, I can see myself laying back in an easy chair, can of ... coke in hand and watching the jets fly by. Lots of good fireworks displays too.
Must hurry, missus says we must be in some underground bunkers by dark so to avoid the 'boogy men'. Can't understand what she is flapping on about.
Yes, Bagdad certainly is an exciting to retire to !
