New guy here, just bought a 2009 G37xS sedan. I WAS a TL guy but I can tell you after driving this G for only a short period of time, I am very pleased and happy with my new choice.
I hope to learn a lot on this forum. I'll try to get some pics up of the new ride later on tonight.

 

welcome aboard! I think there are quite a few members on here that came from a TL, myself included. I had an '06 TL prior to my '12 XS sedan. As nice of a car as the TL is, it's fairly boring, at least it was to me. LOVE my G. Any plans for it w/ mods?

 

No plans for mods yet but I'm sure that will change as I get used to the car. I would like some 19"s and maybe a better/lower suspension to get a little more of an aggressive stance.
What are some popular mods for these cars?

 

probably the most popular mods would be tint, rims (Vossen, S-Coupe OEM, Volk), springs (Eibach or Swift), OEM front lip, Sways (Hotchki or Eibach)
