same here, beside the new painted lower valence, the exterior doesn't do it for me...especially the front bumper. That's why I bought the 04 with the nismo kit which looks better IMO.
Somehow, I think '05 looks more "japanese" now then the 03 & 04 style
The interior is nicer tho but it doesn't have the got-to-have-it factor

All things considered, inside and out, I think the 05 model has lost the edge that the 03/04 have. The 05 looks too sedate, too calm, too Lexus. Sure there's a couple (and that's about it) cool things on the 05, but personally I'd take an 04 over an 05! Seems many people like the new wheels on the 05. YUCK! They look like they came off an old Buick...blah, blah, blah!
