In today's market, I always say, buy the owner not the car, find a technical fellow with a well maintained ride, and get it from him. It did come in petrol, majority in the market are petrol, those are a special kind of pain to endure. If I were you, I would prefer a VX Limited, let it be a Prado or a land cruiser, at least it will have local part support.
As for a Prado, I recall a white VX Limited for sale in isb, lovely looking vehicle, multan number, worth a look.
Also, if comfort is what you want, you can easily find a well maintained gen 4 pajero in your price. Not to certain about the body parts availability but mechanical and electrical support is available for the dewan ones. Definitely worth a look.
