I'm 60 with pre-existing conditions. Quoted $6,000 per year, excluding pre-existing conditions (which are the ones most likely to kill me).
Have set enough aside to hopefully cover at least one major illness/injury. Saving $6k per year, I can set aside 1 million Baht every 4 years for medical care in the future.
I paid 310 Bht for both licenses. You need medical report and proof of address. No driving test, just perception and reaction tests. All done in 30 minutes.
