Are infiniti G35 coupes reliable casr?

I bought my G about 6 months ago, it was a high mileage car when I bought it, 131,000. I bought the car under the advice of my mechanic (who has owned two), he never had a problem with the first but had to replace it when it was stolen. He has never had a problem with the second either, older and higher milage than mine, 145,000+mi. I autocross (legally race) mine on the weekends and still depend on it to take me from school home (45min) or to take my girlfriend home(2.5hr) and it has never let me down. Very comfortable ride and great hadling on the race track, I dont know how they do it but i dont complain!
