clay1, I am glad that was an easy fix for you. ;) Trina, sorry that wasn't your case. few more things I could think of for you. - something under the passenger seat or door? - contact surface betweent the a-piller and the dash? (try stuffing some kind of foam in between temperory to see if it goes away). - Window stopper. Try with passenger window down at various height and see if that helps. - Glove compartmet latch. Try with glove compartment open. - blower. Try with fan on and off at various fan speed. good luck!

something in the glove compartment?

don't know enough about the 350... but your typical engine performance upgrade would be intake (not much here), header, high flow cat, mid pipe, and axle back. Then check out some engine management. but seems like Lexus has some pretty tight ECU, not sure if there is anything available for aftermarket. force induction is always a good way to go, but not sure if there is a kit for it. even if there is, I think your CR is too high for FI. might have to run on a very low boost, then might just well not.... i am still doing research on the 350. I am all for performance, but I don't think I would pick up a 350 to mod it. I rather pick up an STi or WRX TR and mod that sucker out. :)

definitly worth doing. (i would for my next new car) the price doesn't sound too bad. but i suggest you always shop around a little.

Okay, I am sorry if this is a repost but I couldn't use the search button since the minimum is 4 characters... First question, VOLUMN! Where can I find the biggest Lexus inventory in the bay area, specifically new IS350? Second question, which dealership most willing to negotiate with price, be it phone, email, or in-person? Last question, which dealership is the most crappy and should definitly avoid? Thanks in advance! :)

I had the same question and did a little search in this forum and found this... http://my.is/forums/f87/got-headunit-my-2i...o-added-317250/ It's very clean IMO, but it's also too low. I am lucky, since I am still the in research stage and haven't purchase the car yet. And from what I've found so far, I would get the IS350+NV+LL. The question is, how difficult would it be to hack the system for full feature while the car is in motion. The search button has been a good friend so far. :)

as some have posted, on paper, the STi will take you... close, but it will...
