Our PCX white plate had two letters at the top, area under that and "1" under that.
Seems they only have a number for the month, if you want that number you have to wait till the next month for availability.
When we bought the PCX we paid 500bht extra for "1", when the plate and book turned up it wasn't "1", they fluffed around and seems the lady who did our stuff pocketed the 500bht.
Anyhoooo, went to the LTO and told them, they said you can have "1" in two months time, 500bht, go back to Honda and get your money back.
After telling Honda what LTO said they gave us our money back. Our "1" plate turned up as promised.
Mrs. T's weee run-about car has a coloured plate, not "1", but cost 40,000bht, and no, I didn't pay for it....????
