BLACKLS430

Just wanted to say hello to all. I purchased an 03 LS 430 today in New Jersey. This will be my 4th LS since Lexus started making them, although I haven't had one since 1998. I'm looking forward to taking delivery sometime this month and wanted to know from those who have had both earlier and later models what you think the major changes I'll find in driving, either positive or negative. Thanks.
