Buing a car in the UK - living in HK

[Toobin]

Currently I'm living in Hong Kong and I'm thinking of getting a car in the UK to potter around in when I go home (AMV8 or similar). Long story short but my UK license expired in 2012 (just needs renewing) and I was afraid to re-register it in case there were any tax implications for declaring a UK residence - assume I can buy a car with a HK license though?

Also have any of the expats out there kept a car back in the UK? what are the pitfalls? is insurance an issue?

Appreciate any help.
