DMM "Bug". (Assorted Anodised colours. I have some Red and Grey as pictured...) Great all-rounder with exceptional friction. IMO)
NB NEW lighter model. For a short time only and while stocks last...
If you only have a 2wd make sure you stock up on bulk fresh water in town so you don't have to keep driving back and forth on that road every day. I've taken several Hyundai Getz hire cars on that road in the past, it takes forever but totally doable if you have the patience.
