If you need excellent service take your Infiniti here. With my 2003 G35 coupe and almost 161K miles all the major service was done by the service tech: Keith.
Ask for Keith, my 2003 G35 coupe has been the most reliable car I have ever owned. Maybe because its an Infiniti or because Keith does a great job on keeping it in tip top shape.
With that many miles and zero leaks: oil, etc. I hope it will last till 200K miles with no major problems. It still runs great and has cold ac.
