Upgrading from Montero V98W 2013

[Ramsad]

Gentlemen,

am currently using a 2013 late Montero V98W GLX ( Diesel) which I got 3 years back when she had done only 35K +. Now she is slightly shy of 85K, but still in top nick and company maintained to the dot. 

It’s a nice set of wheels , fun to ride with ample power and space. But refinement & creature comfort  wise am wondering whether to upgrade to a Toyota Prado 150 or Land cruiser 200?

My budget is 14Mn which I may be able to stretch another 1/2 Mn. I need something which has equal power to the Monty or more, but more comfortable and refined ride.

i have been looking at a few 200 V8 Petrol LCs. As per the ads I think the best 200 I could afford would be something manufactured between 2008-2010. But fully loaded ZX or AX G special. 

Do you think this is a wise move for me to do the switch? Am I jumping on to a money pit , as the Monty has been very cost effective in terms of maintenance. Fuel is not a major concern as I am getting company fuel pumped. 

And if you think V8 is a smart move what should I be specifically looking at in the vehicle in terms of maintenance and what problems to anticipate 

Or should I bin the V8 dream and go for  150 and call it a day?

thanks in advance guys
