I started out to go test drive the RX330, on impulse stopped at a Infiniti Dealer on the way... I never made it to my appointment at Lexus.
I think the FX is the best of both worlds, and definitely an improvement over the typical SUV (for city driving). The suspension is tighter and has less travel, thus you don't have the roll & pitch of the high center of gravity in a typical SUV.
It can corner very tightly, and has much better accelerator response than my Mountaineer (w/ V8) or GMC ever had.
It's very easy to get into and out of, no folding yourself into a sports car, and yet you don't have to climb way up into a SUV.
You'll never be able to blaze new trails in real deep snow, cross center medians to take shortcuts, or cut through back fields to escape the cops chasing you for that 120 mph speeding ticket, but then how many of us really do that.... LOL
I say go try them, drive your current Lexus for a few days, then go back and test drive them again. I think you will either fall in love with the concept or not.
And if not, almost all the luxury car manufacturers have car based SUVs now - something for everyone's taste.And isn't most of the fun shopping and looking anyway??Have Fun (and I just turned 50 so I'm not 40's anymore either...),
