I bought this from one of my neighbors who had purchased it for their 16 yr old daughter (who REFUSED to drive it).. they purchased it in May of 2015, nd shortly after it started having issues..I had a friend try and look at it (not mechanically inclined) so we are still at a loss..car has not been actually driven anywhere since I bought it, xcept to move it from their house to mine, nd then from the street to my driveway, nd then from the driveway to the back alley. Engine is rattling/knocking/something..overheating maybe.maybe it just needs to be flushed out? .I DO NOT KNOW WHATS WRONG with it! might need a new motor..might need a new head gasket or tranny...motor is a 2.7, nd is in need of repair, r you can part it out.. has ALOT of good parts!..Has working Remote Start, ar does start and Run, UT I don't know how far you would get!! motor is clean.. inside is clean.. no staining of holes on seat..I do not know if the previous owner was a smoker, s I cannot smell smoke in the car, nd usually I have a VERY sensitive nose to this.. some rust in places (see pics), ut nothing rusted through..clear coat on trunk, nd top is pealing (see pics).. 171105 Miles on it..I am a single parent of 6, nd just DO NOT have the funds nor the time to get it looked at or repaired!.CLEAN title!!
