The car hire places at the airport overcharge in comparison to other rental companies all around Thailand,recently I hired a Toyota fortuner 7 seats fully insured for 20k for 30 days and the following month a hired a smaller Toyota vios brand new for
*****
a month…those are the prices from most rental companies
Use an agent it’s getting difficult I finally managed to open 2 accounts last week bangkok bank and krungsi both wanted rental contract bkk bank wanted letter from immigration proof of residence easy enough to get just a bit of hassle,krungsi at first told me no but then a bit of sweet talk and I had to show the chanote title to the condo I stay at and then i had my account,all in all a lengthy process back n forth,agent will do it for around 3k if you want to save the hassle
He doesn’t have to prove your location for an extension if he already has the visa and currently in Thailand I just used an agent,.I am on the same visa and got the extension for 90 days with just a few photographs and my rental contract it will cost him 8-9k baht with a good agent
