We caught one of these to the next town which was about 30kms away. This was because our tour company forgot to pick us up for our transfer to Acapulco- we met up with the minibus (which was our transfer vehicle) at a petrol station. I think our Spanish speaking taxi driver really enjoyed giving the veedub a bit of stick on the twisty mountain road! As I think he was told to get us there as quickly as possible!
