Hey,Not sure many people want competition spec S15's. they are too expensive for your average joe drifter, and more of a road car/daily/weekend car for 99% of people.
And also I wouldn't want an S15 with holes cut in the floor for the cage if the cage is removed, and its been drifted in comp which will put people off.
I think your best off selling the geo's etc and put it back to standard. Then ask 7.5-8k.
ors current price is £8500 as is, plus the cage uses small box section so there's no wholes in the floor and to top it off the bodywork is super clean or no real battle scars. First person who viewed it wanted it.. Just his wife wouldn't let him spend that much on a car
