so your mechanic that checked it out first is a con artist too ??? very possible ... well , i dont sell cars. but i have watched people lay down cash , get the paperwork done, drive it away without ever having it looked at. then try to sue people 2 months down the road after the thing takes a ****. its a used car with no warranty... buyer beware. do your homework, take it to someone that knows cars before laying down the cash ..easy
if the seller isnt willing to that .... walk away .. even easier
