Scare the hell out of him and get him a baby seat for the back.

haha. get him a quadruple turbo charger

Squash air fresheners! You should see if he has factory warranty before you go buy an intake.

You could always get him an ARC shift knob. Those things are some $.

my type of girl friend... I would say tints for starters, not so sure about the intakes and stuff, after all it's a lexus, you want a quiet sexy, not that racer sexy like you stated. but very thoughtful! Can I share you with him? my girlfriend is too selfish to even think that deep.

how about some nice rims that he was looking into? maybe some nice floor mats. or a gas gift card!!!!!

I would love a gas card.... like money on it and I can spend it. Most of it would probably be used going over my gfs house anyway. Zoom Zoom~~~

Mashimaro seatcovers !! <3 <3

window tint...and those broadview mirrors if he doesnt have one..dont forget the air fresheners XD

maybe change the doorlights and the toplight? thingy? i cant remember the name..haha

damn ure getting ure bf car parts? will you be mine too?

oh you should get him some like springs or something just to lower it

I say you buy him a pillow and a blanket for his car!
Every car needs one!

great hint for a great time. (;

air freshener sadfasdjfksafdsafsd

Okayy.. well I guess I'll add more things that he already has.
He already has pillow & blanket in the trunk. Air fresheners in the front.
Car charger for his phone, iPod AND bluetooth.
Floor mats and floor covers from the Lexus dealerships.

And just yesterday there was a baby seat.
He's already been saying "DON'T YOU GET ANY IDEAS."
O____O

Thank you for the ideas, guys. Keep them coming.
P.S. I know plenty of girl-friends that buy car parts for guys, haha.

Get your boy an Arc Shift knob

It's stylish and doesn't get hot in the sun nor heat.

You could also get
-Broadway mirrors
-Eibach lowering springs
-Wax kit

HAhahahah ><!

Awww he already has an ipod... I was about to say that.

Hmm... how 'bout leds?

I don't know if you'd consider that racy though. =o

I agree...a gas card would be nice lol.

It's get tricky, you never know what he might like or dislike.

+1

on second throught, agreed :X
or if you want...get him 2 baby seats and a small screen for videos? x]
navi system?
titatium windshield wipers? XD
change his backlight?

what about a gps system? lol my brother was really happy when his girlfriend got him one probably because he drives back home and lives like two states away

If you want to get him something for his "show car" then get him some detailing supplies:

autogeek.net has TONS of supplies. If you're going to splurge on a gift, I recommend a porter cable 7424 light swirl removal kit.

http://autogeek.net/po.html

Plus there's plenty of other detailing supplies....waxes, sealants, glazes, polishes, towels, pads, interior sprays, leather cleaner/conditioner (lexol), carpet cleaners, a good vacuum, spray guns, washes, glass, headlight, wheel cleaners/polishes...list goes on and on.

Or...if you were really going to buy all of those things mentioned above (tint $250, K&N $250, Grill $300+?) How about getting something to show off his "show car"...like a digital SLR

Canon Rebel XTi comes to mind...

give him a present in the roomy back seat

Haahaaaaa!!! That would be hilarious! Well maybe not for him hehe.

I've heard some good ones already. I back the air freshener, high quality cleaning supplies, gift cert for a good window tint place, or one of those things you mentioned if you know exactly what he wants.

Mashimaro seat covers... heeeck no! LOL. But what an awesome girlfriend you are. Guys love stuff for their car, but most are very particular so make sure you can return/exchange.

listen to this man =X

my arc knob burns my hand after sitting in the heat

mine faded =[


get some squash freshener and some happy endings for him....
