If she really want is a real SUV with that price range, here are some.

1. 1999 - 2002 Mitsubishi Pajero Fieldmaster (4x4 or 4x2)
2. 1999 - 2001 Nissan Patrol (4x4 or 4x2)
3. 1999 - 2004 Isuzu Trooper (4x4 or 4x2)

However, those are diesel engines and their mileage ranges from 6-7 kms/l. If you want crossovers, then here are some

1. Early 3rd gen. Honda CR-V
2. 1st gen. Hyundai Tucson (preferably the CRDI or diesel variant)
3. Any crossover released between 2006 - 2008

For me, I would pick up the Tucson because it has a diesel engine and better mileage and performance.
