We'll everyone is entitled to be happy and the G35 is a really nice car, but a lease, I hope you don't plan to add any mods to it. Why do I say this, well Infinity is picky and if you loose your warranty because of a modified part on a leased car, they (the leasing company) can demand you to return the car to OEM spec and purchase a new warranty. Allot of details are involved as well but it has happened. I'm sure you'll join there forum and you can read about it on one of there blogs. Just looking out for you that's all and again, G35's have allot of potential. Go for it, but I say purchase it.
PS. I hope you like my LED tail-lights, you'll see plenty of them...(thumb)
