Well if u have 2 options, 1 is to buy a 'genuine condition' car jis engine dhowan marta ho.Body color fade ho gaya ho,electrical problem bhi hon, and not to forget under body mai rust ho,for say like 300k and then u have to spend 100k to make her perfect in every way,plus 2-3 weeks daily visits to workshop.
2nd option,a well cared car,with sound engine (because it was overhauled a year ago),good body color all around (some pieces painted because of fading color),all electrical gadgets working and no rust, for like 400k what would u buy??
on the other hand,woh banda tou apko genuine keh kar beich daye ga car.But ap jab usko paint etc karao gaye tou phir woh genuine tou nahi rahaye gi.
bhai jan i told u,i had a change of mind rather my mechanic changed it for me and I did apologized to you for it,publicly.
As for the swap,yaar she did came with a 1.5L Vtec engine in malaysia,which means it will be bolt on fit.I think u haven't seen a same model city from karachi which has 0-100 timing under 10 sec.and it never hurts anyone to have some extra horses under his hood. Plus gud fuel average.
