New version of GM Tech 2
 

Hello, I have a GM Tech 2 already, but it is the old version, which could only do GM cars, if I need to do other cars, I need to buy another 30MB card. I heard that there is new version of GM Tech 2, which can do 6 brands of cars. I decide to sell the old version and buy the new one. But I would like to hear some suggestion from you at first. Below is the new version of GM Tech 2.

GM Tech 2

Any suggestion is welcome!!
