Qx2Gx

Hey all, I've been doing some research online and remember from a few years ago the rx330 offering a "performance package" that among other options included 4-wheel air suspension and a sequential shift auto transmission. Was this package only available on 2004 models (based on the research that's all I could find) or did the package roll over to later models (2005-2006). This could be a deal breaker in whether or not I decide to opt for an rx or a gx. Any help from you rx owners would be appreciated, thanks!
