Well I´m pretty sure I´m going to purchase the CGL 125 TOOL here in méxico. It´s only around $1,200 usd...sure it doesn´t have the best suspension, tires, hp, etc...but it´s the cheapest and of the ¨cheap¨ bikes it seems to be the most reliable. Only thing is I think I will probably need to change out the front tire before I head out because I´ve heard that with water it is extremely slippery...and so it looks.

CGL Terra (Peru model) is more suitable for bad road. The "difference" parts in that model can easily modded by yourself in Latin America because there's similar chinese model.

Here on the other side of the broder in Guatemala they have the Todo terreno CGL, but it´s around $300 usd more and I didn´t really notice much of a difference other than the tires...what are the actual technical differences between the two models?

Not much difference. Tires & front mud guard ONLY.
