There are few questions to be asked before proceeding:
- How many cylinders? Mind that more cylinder means more gas drained.
- Mileage? Toyota/Honda are good even after 150K but others?
- Anything that needs to be changed, repaired? (usually they say no)
- Automatic/ Manual transmission? Changing gears
- Power window?
- Any rust or damage?
- Title clean/ in hand?
- Ask for CARFAX report (thanks to Amit)
- Take it to a mechanics before final deal (thanks to Amit)
