Too bad you haven't been able to enjoy your Special, Tony! Haven't driven the LS 430, but I'd be surprised if the Special isn't a reasonable contender to the 2006 Lexus. Fuel economy might be better with the Special, and I doubt there would be too many downsides. I have gotten almost five years of trouble-free (and fun) driving from my 18,000-mile Special. Good luck with the sale!
