I am considering buying a 03' Infiniti G35 sedan ?

I have a few questions & concerns. This car currently has 117 miles on it, which is high mileage but the overall price is 9,995 is that a good deal for a car with those miles? How long do these sorts of cars last? And how hard is it to manage an infinti & when problems arise with the car do the parts cost more or the labor since its a exotic car so they would say? Thanks.
