Don't be fooled, it is a Toyota Landcrusier thats a 92' with a Chevy 305 under the hood, if you like going off the road, I'd pick this, or something like it.
Since you said you want an SUV, I'd also look into an old Landrover possibly, personally I'd get either the land cruiser or get a 4runner SR5 with a stick(an slightly older one) and then whatever I saved from the purchase rice i'd drop on a lift kit, some new tires/wheels, and a brush gaurd.
but also I have no clue where in the world you are so this might be far away for you.
also if you want an Audi, they are a good choice but can be pricey to keep running, even though with your budget you could pick up a B5 S4.
just throwing out some ideas.
Are you set on an SUV?
