For some odd readon, the MOST engine changed car in pakistan is Honda City : (
every second Honda City you see has engine changed... can't figure out why : ( either the engine design is weak or most owners did not take proper care of it.. but why this car is on the top ?
personally i also think it affects resale value and can cause trouble in future... however, mechanics actually prefer engine change over overhauling the engine... and some people told me it's okay to buy engine changed cars if they are in good condition and proper paperwork is done, no issue ... however, i still have a skeptical view about it ..
waiting for more experts to shed some darkness (light) on the topic
