so i went to look at a 240sx s13 today because i want one really bad and it was a genuine pos because of how old they are but besides that.. i went to test drive it and it shook really bad at idle(i know thats a bad sparkplug or injector) and that is not bad but i saw that the whole front of the engine block has oil residue and the owner(complete idiot) said that she hasnt changed the oil in a while and she just keeps topping it off and thats it..
. when i was driving it, there was no smoke or anything, it smelled like like oil in the car but thats it.. i am wondering if this is a major problem that should stop me from buying the car. if you need anymore details to help me then ask.
thanks
