@Mkimwa -
Golf Mk5 - post 2003... From £4k (@129) = Ksh520k
As you said the volume/popularity of cars frm Japan... hence competittion etc
Anyway as I showed earlier start off here
http://www.autotrader.co.uk/ Here you will be asked to enter a postcode
Use one of mine NW2 5AB. Ensure you also include the space. ...and you're in! Select details of vehicles you're looking for.
http://motors.ebay.co.uk/ is another site.
Be diligent,dont trust everything you see. There is a lot more you need to know.
Then you need to consider inspection (JEVIC) and Freight and Insurance.
Let me know if you have problems trying to access the sites.
