before buying a second hand car ts, check the following:
a. official receipt - this should be clean... make sure all details are right...
b. certificate of registration - make sure this is updated... you don't want to be caught driving an unregistered vehicle...
c. engine - make sure it is in very good running condition... if you know a lot about engines, then you know what to check, but if not, i recommend you bring along a good mechanic...
d. chassis and body - check for rust, wear, damages etc... an advanced case of rusting could cost thousands of pesos to repair in the near future...
e. tires, shocks, underchassis etc... - test drive to see how the car will perform in general...
f. interiors - as much as possible, the carpet, sidings, ceiling, upholstery etc. should be clean and still presentable...
remember ts, you are buying a 2nd hand car... so don't raise your expectations and standards too high... goodluck...
