The guy speaks English he said we can just change your air-con filter if you want but the system is a mess, I saw the airfilter which was a real mess.
He said the inside system is very dirty and we will check the aircon fluid.
The trucks 6 years old so i just said OK get all done.
Had engine oil and filter change, wheels off and cleaned, all brakes cleaned and hand brake adjusted.
External rad cleaned, underneath checked including steering rubbers etc. 4,320 baht so not so bad the 1,800 included just seemed a bit much.
