I will agree with you here in Phuket BOLT have been superb, I had family here who were staying in Karon and I live in Rawai so I have used a few times and all decent cars, one day was a brand new MG SUV, then another day was a Fortuna,
Taxi's from the hotel where my daughter was staying wanted 450 Baht, That was 200 baht more than BOLT,
The hotels are just as bad, for an airport drop off they wanted 2000 Baht normally a 1000 baht
