I took this car in on trade, and I think it's a pretty fun car.

This makes me think I should build up a few more like it and let our customers take advantage of our financing and lifetime engine warranty.

What do you think, would people be interested in buying a car like this off a lot, or do people prefer buy a stock car and add parts to it themselves?

Thanks for your time, all.

 

Again, link is useless. I wouldn't put on body package unless customer wants one. Inform him when selling. Free advertising, again.

 

Short answer? NO!!
Most body kits look stupid, do not fit well and will NOT raise the value of the car. In fact they would more likely reduce the value.
Then there are the few (customers) that might like it and the many that would not.

 

Agreed. I think you'd be better off adding functional items like heated side mirrors. A direct swap to those would run about $200 in parts but would actually increase the value of the car.
