hey guys im looking at buying my first car which happens to be a jeep cherokee and im looking at a 2000 jeep cherokee. it looks very clean inside and out,it has 141,000 miles on it but the only thing is it is leaking a tiny bit of oil around the pan and it looks like the tranny may be leaking a tiny bit of tranny fluid(if it is tranny fluid) as well but its not dripping at all it just looks wet and i took it for a test drive and everything works fine. The guy is asking 4000$neg and its from a used car dealership and my question to you is, will this be a bad thing or is it a bad thing? sorry if this is in the wrong section. but i really hope you guys can help me out with this . oh yea heres the link http://www.taillightmotorsinc.com/De...Q41LL4VXNB4%3d
