Both are diesel and have an upgrade.

Montero will have 2 din stereo system and improved engine when it comes out 2nd week of Feb 2011. Thats what the dealer told me.

Sta Fe - already have 2 din w/ GPS. Very good reviews. Some says the steering is very soft which could be annoying.

Other says they have both very good suspension.

Tried the Fortuner and its really matigas and matagtag. I also dont like the seats. It very narrow for me. Tigas din ng upuan. backside seating is also very uncomfortable. Pang porma lang talaga Fortuner.

I am currently using Xtrail for 5 years now. Ride is very comfortable. The seats are wide and is very comfortable even at the back. Nakakatulog agad pasahero ko in long travels.

Already Checked the Santa Fe and it really feels good inside. Montero feels very tight inside. The xtrail is bigger inside. But havent check it thoroughly yet.

Need your input guys, I will be buying on Feb 15,2011.
