LOOKING FOR A CAR

Hi,
My name is Jing. I just came from China and started my new life in Rochester. I am a visiting researcher in Cardiovascular in Alfred building. I'm looking for a second-hand good condition SUV. I would appreciate any help if anyone would sell or give advices or anyone would help me to find one from the local dealer? My budget is 7,000-8,000. Please contact me if anyone would help. Thank you!
Best wishes!
