If the brand doesn't affect your decision, definitely go for montero. But if it plays a big role, then consider Fortuner, as its after sales is more reliable.
Having own 2015 montero. My vote go to fortuner. Both are good but you can really appreciate toyota in the long run had many problems with my montero and for my 2014 ford everest still on sale even though i slash the price almost 60%. Its a matter of your preferences when choosing cars.
Buying your car isnt just of blog or reviews is about what you want and need. Yes for you montero is good and value for money but for other is not specially for me i own previous model and i sold it. I own to mitsu and believe the maintenance cost exceed the isuzu and toyotas. Enjoy your ride and dont just judging other car just you merely test drive it. Own one then you make judgement. 😁
