My thoughts...

1. Yes, get a ride in another Boxster for comparison.
2. Try adjusting tire pressures. Try 27F and 33R. Depending on the tire, the fronts can be harsh even at the stock 29psi.
3. Tires - what make/model tires do you have? Some ride very hard. My Michelin PS2's rode very comfortably as did the Kumho Ecsta XS's but the Hankook R-S3's that I have now ride like a truck (but they stick like glue - everything is a tradeoff).
4. Your Boxster is never going to ride like a Lexus. My Boxster (competely stock) rides much harder than my 325i. In fact, the 325i feels like an old 70's Caddy floating all over the road in comparision.
