I would get some gutter guard and make some grill inserts....cheap to make and they look nice....
a nice aluminum dash kit would look nice....
Get a aftermarket spoiler with a led 3rd brake light in it....they look nice and don't look ricey.
Chrome edging on the doors would help it look nice...plus it helps against dinging other people's doors...
Projector headlights do look nice....
Stainless steel side body paneling....looks great and yet not ricey...about $115 a set but makes your car stand out.
Rims are a must..
Some basic clamp on stainless tailpipe ends....and no they don't look foreign cause they are only as big as your previous exhaust tips.
Paint your brake calipers...cheap to do yourself and looks great!
Stainless steel wiper blades...
www.crutchfield.com sells some and they are about $15 a piece and comes with 3 refills. They are made out of silicone and work very nice.
Engine mod wise....
Cold air intake.....you can find them cheap on ebay....gives you better gas mileage...around $50
Get a AEM bypass valve for the intake so if you hit a puddle it doesn't cause hydrolock...yikes!
High performance ignition would be nice..gives you a little more hp and gas mileage.
