Tips on Buying Cars: Nissan Maxima, high mileage car, mileage vehicles

Question
Hi Goodmorning
I am potentially looking at 2 used cars. Both Maximas.3.0 And both checked by my mechanic.
Ones 2002 3.0 blue color and has less than 40,000 on the odometer. Good condition, my mechanic seems pleased…
need some slight shock / bushing work in the front tyres/ lady driven/ the automatic open does not work, it needs the key to start, window too has some problem as in when putting it up it goes up fully but comes half way down again.
The other has 115,000 on the odometer and is well maintained , as in serviced every month. The owner is a friend and I know that he is very nit-picky when It comes to his car.  And the mechanic says the car is good.

Im a bit muffled about the mileafe  

Answer
I'm not exactly clear what your question is, but if you're asking me which one you should buy, it all depends on the price.  I personally am not afraid of high-mileage vehicles as long as they've been maintained; they're usually a good buy because most people think a high-mileage car is used up.  You'll have to research some sites like Edmunds.com to find out what you should pay for either of these- only then will you know which one is the best deal.
