Yeah, go for the Stealth, you are guaranteed performance speed without the pup vs maybe getting close to stealth with this update but at same $. I am not sure how they will get around the fact that if they make these AWD LRs close to performance speed you will have almost identical models in terms of price but different nomenclature, with P3D- obviously the more premium in terms of name only. Plus with the P3D- you are actually buying a Performance model, vs an AWD that is slightly faster than normal AWD.
underrated comment. The residual value difference alone is worth the Performance stealth premium.
