I need help making a decision whether to get a 2010 G37x or a 2015 Q40 AWD. The G is going for 8800 with 120k mi while the Q is 7999 for 115k mi. Right off the bat the Q is already a better deal, but the thing is the G is coupe, which looks better, while the Q is sedan. But I guess I can easily make a Q look just as nice with some accessories. Nevertheless, which would you guys recommend? Since the Q is 5 years newer I like to assume that it has better technology inside and maybe outside too, but I hear that the difference isn't too much. Do they both have the same driving feel? What is one top reason for each car that would determine them better over the other? I'm sure they perform generally the same. They're both pretty good deals and I'm completely torn in making this decision. The average person would probably get the newer one just because it's newer, but is it really that much newer? Please help.

 

Are you able to get any service records? The main thing that would deter me from the G is the possibility of a failing oil gallery gasket. Prior to 2013 they used a paper gasket that commonly fails around that mileage and requires the front timing cover to come off to fix it.
