Hi all,
I am only posting as I did benefited from the forum, managed to get some contacts off this post for my Taiwan trip last week. I engaged 3 different drivers during my Taiwan (KHH-Taichung-TPE) trip, of which 2 of them was from this post. One of them is a 'famous, often mentioned' and the other was from a post that some were accusing as fake. Both were same price at NTD 3500, the famous one did charge me extra for exceeding an hour. The other driver did not charge additional for the exceeded 2.5hours.
I would say that both drivers were pretty good. The famous one was very polite and knew the right thing to say. The other guy was sincere but not as smart in portraying himself in a good light. In conclusion, I think each to their own, it is all about your own needs. I suggest dont just omit those drivers whom name were posted by those newbie of HWZ. Most of those posts are obviously from Singaporeans, I highly doubt that Singaporeans will make fake posts for a small amount of money(finger-crossed). However, if you are looking for a smart and polite driver, then those few whom are widely mentioned would probably suit your need.
Those who are travelling on budget, can consider hiring driver off the road(Kaohsiung/Taichung), most quoted me NTD 3000/8hours for 4 pax. I would also suggest travelling via HSR(get tickets via KLOOK) as an option for more convenient locations, save a lot time and money. Firstly, you get to experience something different. Secondly, you wouldn't need to pay for your driver's accommodation and food for making him travel out of where he stays (they usually add it in the amount that they quote you).
P.S:

I have 4 Fruit Picking Vouchers from Taiwan Tourism Board (didnt had time to use it) that I would like to give away. Anyone whom are interested, can just pm me. It is valid till end of Dec 2017.
