If your happy to consider a petrol 200series why not consider a Y62.
People are currently asking 45-50k for series one ST-L's
I paid 52k for mine over 3 years ago!! I rekon in 18months you should be able to buy a tidy one within your budget.
$49k is surely taking the piss!! Though if they are still fetching that money I haven't lost too much to depreciation
But it will probably be newer than an equivalent priced petrol 200sereis, has a lot more power and a better gearbox not to mention its pretty bloody huge inside!!
In fact if your prepared to consider a petrol powered option between Nissan and toyota the Y62 really is the default choice!
If you like Prado's and are happy with petrol the 4litre V6 is a cracker of an engine too!
If you like GU patrols the 4.8 auto solves the woeful performance issues of the 3.0CRD, but be warned, the fuel use horror stories are true! At least they were for my 4.8, would still buy another in a heartbeat though:)
