WANTED: WANTED: expedition or suburban

Im looking for a large size suv, either an expedition or a suburban. I currently have an older explorer which I love, but it is now too small. I need something with a larger cargo area to fit a wheelchair and other equipment. Must have leather seats, and must be an automatic. I have a very modest budget, prefer to stay at or under 7,500 but may be able to go up to 10,000 for the right vehicle. Would prefer something with less than 200,000km. Must be safe with no major work needed. Willing to look anywhere on the lower island, could even go to the lower mainland for the perfect vehicle. Thanks!!
