Be very careful about purchasing cars on Ebay. The seller almost always include something like "10% of deposit due within 48 hours of auction close. Full payment required within 7 days". However, if the vehicle is in a remote location, there is no way to complete the PPI, and arrange payment in such a short time. Some of the sellers will purposely stall the inspection, but still require the full payment in the giving tight schedule. You'll either lose the deposit, or find defects later because the transaction is rushed.
