Drsultan. Since your have a VXL, it means the powered options you already have. Consider the following.
Get a good quality (exact matching) dark gray cloth and have customised seat covers stitched from some good seat cover wala (azhar shaheed market pindi or melody islamabad).
Get CULTUS written exact cut-to-size carpet mats.
Intall yellow colored fog lights (round ones).
Change the tyres (165R13) Yokohama C series or Dunlop Lemans or Eco series.
Alloy Rims (you already have from the company).
Think of changing the steering. Replace it (if technically possible) with 2001 GTI, 1600cc Baleno. Best 4 spoke steering in the line with S (suzuki) badge as well otherewise go to Sultan da khoo & look out for a imported esteem's steering.
Install good quality rear speakers.
Install courtesy lights in all four doors.
Play with the number plate. Check out font options at samad brothers aabpara (corel draw expert aurangzeb).
Can install a smoke cleaner and map reading lights in the roof.
Replace the cassette player with Pioneer's MP3 player.
Change headlights with Halogens (for brighter night vision).
Place cool/hot box (small size) 3 to 4 cans capacity under the seat or in between the front seats.
Replace the rear view mirror with day/night type one (if VXL has not got one). It would ease the night driving.
Have the side mirrors painted with the car color.
Replace the muffler with chrome.
Have 2 sparking lights fixed in the rear reverse lights to work when brakes are applied.
Have the frames of all four doors painted black (if the color of the car is already not black).
Install two reflecting lights at the back end of the rear bumbers (see 2003-2004 accord for reference).
Have a sun shield installed at the upper most edge of the front windscreen (3 inches) preferably same color as the car or light green.
PS. No cheap accessorising like TYPE R stickers or your name at the back or ribbons.
Keep the car extremely clean, gleaming, shining and "wet" all the time. Thats the biggest tribute you give to receive applause.
