For ^ k to me it better be in A1 condition, no scratches, no leaks, idle and run smooth no more that two cranks to start, glass perfect, interior perfect and no smells, tires and alignment shoudl be perfect and the exhaust system should be rust free. Thats when I would consider anything above 2k. Also how good of a mechanic is he? I have never been ASE certified in my life and have no formal schooling and I can guarantee a engine for 6 months.
