The car turned out to be a short wheel base Jeep Wrangler, with 4.2L petrol engine (capable of doing roughly 200 miles on a full tank of petrol) and canvas roof (that leaked!). It did serve us well though, so can't complain!
That hill at the background has been featured in a music video made by Sigur Rós - "Glósóli". We were driving around looking for a different place and found that hill and the cliffs; They're so particular that it's not possible to confuse that with anything else!
The bridge is built over the river which starts as the runoff water from the melting glacier. We've seen a video of a volcano erupting below the glacier, which caused the ice to melt and produce so much water, that the bridge was destroyed. This one must have at least 1km in length and looks solid enough - when you see that and then watch the video, you can understand the sheer power of the water!
