I dealt with Jacks motor once and walked away from a vehicle so take what you will from my one experience
Advert was for a 2005 Alphard, posted in FB / 28 car.com etc, called up and asked about the car and arranged to go their garage in Kwai Chung, arrived there and after looking over the car and asking about it, it was actually a 2004 model, big difference in gear box from 4 speed to 5 speed.
I went through the checks and one of the windows was working properly, one of the electric doors wasnt smooth, I HAD to point these things out to him and off course he said he will get them fixed before I take the keys hmmmm
Typical salesman, he started on going about it wont be in the shop too long for the price he is selling blah blah blah.
The year thing was the worst deception and he came out with the yah yah its actually 2004 but the price is cheap and no way will you find a 2005 for this price blah blah blah, he probably paid 1/2 the asking price or less as trade in for another car he sold LOL
Walked away, please note this was the Kwai Chung shop, i see they have 3 sites so no experience from the other two shops.
