Thanks for all the intelligent replies...sometimes on these forums you get smart a$$ remarks rather than just smart ones...I think I am leaning towards keeping my G35 because...
1. I enjoy the car and if I am going to put my money into something...I am going to enjoy it.
2. I can see the cost benefit (unless I do what someone sugguested by selling my G35 and buying something cheaper) but I plan on keeping my car for the long run.
3. My car will be paid off in a couple years so later I will start putting money in my pocket...rather than the banks.
SO...in conclusion...I hope that my problem has helped other with theirs...Fly safe!!!
