It is available in the previous pages. One of them is Pudding (Taipei) +886 955 577 675 , the other is Wang Chi Chieh (Taichung) +886 917 522 616
I just came back from Taiwan. Same as you, based on the other Bro's post in this tread, I engaged Wang Chi Chieh (Taichung) +886 917 522 616. I am very satisfied with his service. The bro's post was not fake, neither is mine (although this is my first post in HWZ after reading the forum for years, it does not make sense for me to get a single cent from him for recommending him). I found his service very good for me to share with fellow Singaporeans who are looking for driver in Taichung.
As you mentioned, he does not know how to package himself as he is a humble senior humorous Taiwanese. As my family is 5 with luggages, so we need a 9 seater car. Hence his price is higher than what was mentioned here but still cheaper or same than what other drivers (including some recommended in this forum) quoted me. His quote is Add time, Add Places, No add money. But I would not abuse this as he need time to rest (for our safety).
He propose places to visit for my required two days Taichung travelling. I also did my research. He is flexible to accomodate my requests. My family travel leisurely, so we choose the places most interest us. I also booked hotels next to Night Market so that I can travel in his car to as many places as possible.
Initially I thought of using him only for Taichung, so I plan to take train to Taichung, and ask him to pick me from the train station. To my surprise, he propose to pick me up from Taipei. Hence I manage to squeeze Yeh Liu Geo Park into my itinrery, and he brought us to 新竹城隍庙 for famous fried beehoon for lunch.
My second day was from Taichung to Cinjing. He actually suggested to me 鹿港 which I have not seen people put it on the way to Cinjing.
Initially I thought I would end his service at Cinjing and I will make my way to Kaoshiung myself. After seeing the complicity of transferring buses and train, I added one more day of his service from Cinjing to KaoShiung, so that I have chance to visit 台南。He is very knowledgable about the places and suggest good places for meals.
As I mentioned, I do not have other drivers to compare him with. But my family really enjoy his sincere services.
