Are you flipping it or keeping it for multiple years at least?

If you are keeping it, build what pleases you. You will spend over $5K by the time you add the flares [correctly] and buy wheels to fill them. You will not get back $5K when you sell. You risk reducing the number of prospects, but you might increase the value to a certain segment by, say, $2K. Overall, the market most rewards original cars.

And Rick is right: an SC has SC flares, so you get the esthetic you want without altering the car. Difference in price, sure, but you have something you can drive, rather than waiting for body work.
