Want to TRADE: 2000 Daewoo Lanos Sedan for bigger vehicle.

I have had this Daewoo Lanos Sedan since brand new off the car lot in April 2000. There are 2 very small star chips on the windshield and have been there for several years and have not gotten any larger and are not in the drivers view. The dashboard has 4 cracks in it because of the sun beating down on it. In 2004 an Auto Starter was installed into the Daewoo as a gift for me and it works GREAT. The small plastic panel between the driver window and passenger window cracked in half and the top portion is missing, so I had to cover it with the same color of tape. My Daewoo has been maintained constantly as every car should be. I have all papers in hand from all repairs since I bought the car. All upolstery and carpet inside of the car and all the seats are in perfect shape and are very clean. Original radio with cassette player was replaced with an upgraded radio and CD player.
My reason for wanting to EQUALLY TRADE my car is because I now have to use a wheelchair and my wheelchair barely fits in the trunk of my Daewoo and it does not fit in the back seat of my Daewoo. I am looking for something in the size of a Jeep Liberty and not much bigger than that, and nothing that is a gas guzzler either. My Daewoo get 24 HWY miles per gallon, and it's AWESOME on fuel anywhere. I love my little car, but I have no choice but to let it go. I can't afford to buy a used car because I'm on a fixed income being on Disability now, and I have a very strict budget, so I'm trying this BarterQuest. Can someone PLEASE HELP?
I am posting this late on Monday night 11/29/10, but will take photos on the morning of Tuesday, 11/30/10, and I will post them ASAP afterwards.
