I crossed from Turkey via the Bazargan crossing on the 14th.Touts (money changers) on both sides but help not needed. Easy out from Turkey and not too complicated entry to Iran. Being British I had to give finger prints ( visa collected in Istanbul and prints not taken there ) and then the import formalities. Other drivers help showing where to go first.Tip: make sure you have passport photocopy ready. Nothing asked for by the Carnet man although it was obvious from his drawer full of cash what was going on with the "helpers" . Welcome to Iran and you are on your way, that is untill you reach another gate where I was informed that another stamp was needed on the back of the form. The officers try to introduce a helper but I refused and went back and got the stamp.Nobody asks for insurance but don't go to the Iran Insurance office inside the gate as you will be surrounded by helpers/translaters and every other kind of low-life and they will tell you minimum 1 year for 100 Euros. Just after the gate is a roundabout and directly across is an office building ( Sofinco or some such name).The sign is in English lettering so is easy to find.Here you will get the insurance at the right price, ( unless you tell them the wrong price that you expect to pay).The touts are not needed and if completely ignored are not too persistant.
There are hotels in Makou (15kms). Fill up on the way. I don't have a fuel card and it hasn't been a problem, somebody has one. Remember Iran is one and a half hours ahead.
The roads are excellent and the drivers are maniacs.So far a beautiful country.
One other thing, ATMs don't work with foriegn cards so come prepared.
