1)Super/Turbocharger kit
Duh.
2)Body Kit/Hood
Wide Body Kit would be nice *Drool* Also I'd really like to see a kit that replaces the whole front bumper to make the emblem and grill a little more traditional. I also want to see an evo style hood personally.
3)Headlight/Taillight
I'm liking some of the ones I've seen but as I've read elsewhere they should make taillights that are flush instead of buldging out an inch, maybe euro/altezza just for variety (I know they are ricer and I'd rather not see too many riced up Camrys) but depending on how its done it could look ok.
4)Spoiler
Although I love the classy lip spoiler, I'd like to make my Camry slightly more aggressive, I'm not sure what other type of spoiler would look good on this car though. I have seen next to nothing in this department.
5)Manual Transmission Swap for V6
Row row row your gears gently down the road...
6)Basically anything to differentiate my car from the millions of other Camrys while making it look better 
.
More choices the better, so far its basically 1 or 2 aftermarket options if any as far as I can tell. I miss the looks I had with my slower, smaller, less efficient Mitsubishi 3000GT lol.
I had thought Camrys would have a good aftermarket since they are only the best selling car in North America, but I've read the contrary on this forum. C'mon aftermarket support! I think this Camry model deserves it.
Anything else I'm missing from this list? Can't think of anything else atm. Maybe this will give those aftermarket companies some ideas/incentive (I could only hope :P).
