Some new SUVs N 4WDs in the range of QAR75k-80k are Suzuki Grand vitara, Nissan X-trail, Kia Sportage, Kia Sorento and Hyundai Tucson. Of all these, Kia Sorento appears to be the best.
However, if u go for buying a used SUV/4WD, u can get some good models from Nissan, Toyota and American Manufacturers. U may also find a Toyota Land cruiser from early 2000 models.
