I have 2 GXs, an 05- 470 and a 17- 460, the 470 is a better quality rig all around, about to sell with 350,000 plus on the clock, heater core finally went bad and I don't want to invest any more money in it.

Still runs and drives great, by far the best thing I have ever owned.
The 460 is good as well, just not the same build quality as it's older brother.
Has a chain instead of a belt, no rear air bags but overall a very good ride.
