It must have been at least 15 years (to month) when imported, so that makes it a '90 or '91.
Those pretty headlamps with the yellow reflector in the inner side fogs have the wrong light pattern for North America, and are not DOT or SAE approved and must be swapped out to pass a thorough Alberta out of province inspection.
No "turbo" badge on the front grille, "WAGON" decal on the rear side instead of "turbo" decal, relatively small exhaust pipe, and sliding rear windows: make me think that it is not a diesel.
For price, find the price of similar LX450s, add some for a winch, and subtract lots for the RHD (not becuase RHD is bad, but becuase it will cost you more for RHD specific parts, will not be as easy to resell, there will be expenses to get it to comply with Alberta regs, and you will always be a target for vehicle inspection officers), and add a little if you like the uniqueness of a RHD gasser.
If you become serious in buying a JDM Cruiser, I'd suggest that you carefully include in the purchase agreement clauses that make the seller responsible for ensuring that the vehicle meets all provincial regulations - this one appears not to.
In BC, even with a recent and valid inspection, you can still be pulled over by the police or CVSE (commecial vehicle safety enforcement) and ordered to redo the inspection at your cost if they "think" you have a safety issue or may not comply with the regulations. I believe it is the same in Alberta.
