Hello, A couple thoughts that might prove profitable;
1) A body kit for a 1995 to 2001 Metro/swift 2 door I Believe would be the most lucrative for you. A more aggressive tront and rear cover with provision for a common after market fog lights I Believe would sell. (something similar to the mark 2 but brought forward to fit the newer generation,) along with some ground effects (Something say with a twist behind the door flowing into an air vent just in front of the back wheels) To my Knowledge no one is (Or possibly ever has ??) made a kit to fit that generation car.
2) Once item one is established, add a kit for the the four door sedan, Front cover would be the same as item #1, ground effects and rear bumper would be similar to #1 but would need some modifications (Wheel base longer, Rear bumper side panels longer etc.)
3) I would be a player for a body kit similar to what was put on a swift GTI , But made to fit a 94 4door swift sedan
4) Also to start with, repro ground effect kits for MK1 & MK2 GTI/GT 2dr, that are reasonably close to original but differ enough to keep the Eire of the patent attorneys from being raised. (Just add Bacon bits

) I figure would be a "Can't Miss" Item.
Again, I Believe there would be no shortage of desire on the part of most members, to purchase kits, But the ability, (Read CA$H) might be a different story.
Good luck with your venture, Keep us posted, Maybe you might get some be tentative commitments on some of the above, ideas. How about it?? Teamswifters????
Best wishes, Jonathan
