ok for the stuff you're looking for which are all show and no go... which is ok.. cause we all like the bling. you can get most of those mods on ebay. like PIAA bulbs, clear side markers, head lamp bulbs at a very reasonable price.
i would recommend going to the maxima.org group deal forums for the performance mods at the best prices available. for a newbie max on a budget like yours truly. i would go for the rear sway bar and front strut tower bar first. along those lines you can squeeze in some hyper white bulbs for the clear side markers and interior lighting.
if you want an intake, i guess the frankencar a short ram hybrid style that is very popular which the org is having a group deal on. or you can go for the injen, which is a cold air longer tubing going down the engine bay that looks and sounds great. i have it and hightly recommend it.. a bit pricey though.
after that, it all depends.. do you want to spend 250 for tints.. or 250 for a Y pipe installed?.. do you want rims? wheelmax.com is having a great memorial weekend sale on its stock.
for fog lights i'd go for the piaa, preety much they make the best bulbs for fog lights.. yellow ion crystals, platinum super white, or extreme white.. depending on what you're looking for, you got to go to their sight and do you homework. but look to buy them from ebay.
for head lamp, i have sylvania Xtravisions bright white halogen, best bang for the buck at 10 bucks a bulb, if you want the blue halogens, sylvania makes the cool blue at about 13 dollars. anything else than that is crap, unless you buy piaa head light bulbs at about 99 dollars a pair and wish you never bought them.. they also make HID kits at about 300 for the cheaper ones. since you drive a 5th gen you could even get a 2k2 or 2k3 stock HID set up for your ride
for your year max i dont think they have clear tail lamps, but, you can look for SE style tails at salvage yards or even at the for sale forums at the .org or at your local dealership if you hate your stock GXE tails that much.
another great cheap mod which i enjoy everyday is my broadway mirror. it clips right over your stock mirror so you dont even have to remove your old one and it makes your rear viewing a whole lot better. under $20
for exhaust, springs, shocks and struts, strut tower bars, rear sway bars, electronics, dash kits, clutches, flywheels, UDPs, leather seats, nick nack patty whacks, etc. go to the GROUP DEALS FORUMS at maxima.org you will not find anything cheaper than there.. people put together deals where 10 or more members jump in and buy the same item within a period of time (a week or two) together therefor the vendor drops the price significantly enough to give the buyer a good deal.
stay away from rice shops unless you're good at barganning and getting them to drop their blown up prices.
good luck and good modding.
ah, also southwestautoworks.com is a great sight to browse through and gain some knowledge on what's out there for your maxima.. Greg has a lot of deals going on at the GD forum so look out for him, he is a great guy.
after all this typing i need a butt. :smoker2:
