well for the light pod, ur looking at 800 just in lights. if u can find a pod thats another 300 if ur lucky. the 4 lights from Piaa are 150 each plus the harnesses. as for looks, if you only got 1500, its gonna cost alot more for just looks. If ur actaully looking to make a rally car, ur gonna spend about 10k.
2500 roll cage
2000 rally computer
400- skid plates
1500 for all lighting
1000 for other SFI gear
1500 brake upgrades w/ hydraulic handbake
2-3k more for MISC parts
Then you have rims and tires cause you need like 3 sets
so it isn't cheap.
For looks, ur gonna want the WRC body kit if they make it for the sedan, but i don't think they do.
most rally cars don't have body kits unless ur Pastrana, Block, or
people will be more impressed if they see the interior over the exterior. cause some of the best rally cars are completely stock on the exterior minus the lightpod.
just my $.02
