When I went to NZ I managed to find a discount car rental company (public transport there is largely non-existent) and got this bad boy for only £15 a day. Corolla full time 4*4. 1.5 auto so a bit slow but averaged 40 mpg so not too bad. 100% solid car though and drove brilliantly for something with 200k on it!
Also RE post above I am pretty sure Georgia is the most dodgy/dangerous country in the world for driving. Blind overtakes at 1,000 mph on any bend, bumpers seem to be an optional extra, everything is an import (a lot of RHD Japanese stuff, black SUVs rule the road and you even get US 18 wheelers out there! Even being a pedestrian is largely terrifying.
