I have a 2.5 GT 2wd I bought about 3 months ago in Pearl white. That option was another 15,000 baht at the time, maybe not now.
First I will say I'm very happy with the car, it has a nice ride (for an SUV) and the 2.5 has plenty of power. I get a pretty consistent 10km/ltr in mixed driving.
I traded an 8 month old Honda Civic for this car, not because the Civic was a bad car, but the missus did bash in 3 out of 4 corners in those 8 months. In my opinion Thailands roads/streets are not saloon friendly, too many pot holes, high curbs, etc.
Surprisingly the Pajero has a smaller turning radius than the civic, it is easy to maneuver around and has excellent visibility.
If you buy a GT you will get a 7 inch touch screen that will play DVD's from the Alpine stereo, but if you want a GPS module that will cost extra. They will tell you that the ONLY gps that integrates with the screen is a handheld model from Alpine with a patch cable. This is not true. I had a Kamaz unit installed in BKK that is a hidden unit that works very well, it uses the Speednavi map software.
I also had a reverse camera installed that displays on the screen, a very useful option.
A similarly equipped Fortuner is about 200,000 baht more......a lot of coin for Toyota badge.
Hope this helps.
