I can't resist the temptation to buy cheap cars when I see them. This one is a 2006 Nissan Altima . 2.5 l. Automatic. 170k. Guy wants $1,200 for it. Looks halfway decent in the pictures. But that price is suspiciously cheap. Only thing he mentioned is it's losing power steering fluid . Any major problems in this generation Altima I should be looking out for?
