I think you'd be better off getting Japanese import ones. They mostly have air conditioning for a start!
http://www.j-spec.com.au/featured/RoverThis Rover for example is for sale for about $20k, which is approx £9-10k. The car itself costs $11k, or about £5-6k and the additional cost is all the import and compliance costs. The freight cost would be much higher from the UK, same or similar compliance cost so overal seems easier to buy one from Japan?
