On a ten year old car, mileage is a very small consideration. Overall condition should be evaluated by a professional.
In the case above I would definitely take the 93 on numbers alone. For the difference in price all the possible pattern failures could be updated with some left over including head gasket and evap for which both cars are candidates. The newer car is definitely a better product when right.
