Tim, Do an NTSB search by "N" number and see if this plane has any significanf damage history.Unless every aspect of this plane is perfect, $35K is way too high for any 150 / 152. I think this is the sellers opening number so he has plenty of room to negotiate.
Have a good pre-buy done by someone who is NOT linked to the seller to ensure an objective opionion.
FWIW, I bought a 1982 C-152 with dual Comm /navs and 650 SMOH for less than 20K. Deals are out there, dont buy the first thing you see. And dont let a new emeron paint job lead you into buying a flown out, worn out high time wreck.
