I am Leasing. Get some tax write off on my company as well as seem to always want the better tech couple of years later. I also managed to get 4k equity out of the recent Infiniti pull ahead program for existing leases for my 2009 FX and applied toward next car. Leasing can be a good option if you know the numbers in the contract and know your mileage requirements up front. Also remember you only get taxed for the term of the lease not to mention that when a car is at 60% residual you are really locking up substantially less cash.
We ended up leasing when I realized how much I would save in state sales tax, which is quite high in CA. My lease money factor worked out to an APR of about 3.7% and that's only applied to the less than 38% of the MSRP that we were leasing over 39 months.
I will be leasing since I'm not sure if the JX is an SUV i will want to keep for a while. Also the JX being in it's first year of production won't be in the greatest stage just yet, Infiniti will find flaws in it or things that could be added so I will be looking forward to newer JX's in the future.
I, sort of, had that feeling as well with JX being in it's first year of production. But, I had owned a 2004 Lexus GX470, and a 2007 Lexus GX 470, and the only difference I noticed were cheaper materials being used in the 2007 so Lexus could pad the profit margin.... Also, there was a known issue with the drive axle in the GX that started in 2003 and was never corrected despite multiple TSB's issued. Even the 2009 models (the last year the GX470 was produced) still exhibit the same problem which requires you to bring it to Lexus and have them modify the axle....
