Does adding gt flares, or subi conversion, or other mods raise or lower value on a regular 4cyl 914 (not LE's)?
From what I've seen so far, if the modifications are quality (i.e. metal flares, top notch bodywork, quality parts, etc) a standard 914 that wasn't pristine to begin with will have it's value increased. If it's a super example, all stock with no rust (hah) there might be a dip. Or if the work done on it is shoddy.
For a swapped car, value is subjective. If you find the right buyer it's worth a lot, but the number of people in the market for a swapped 914 are fewer than those looking for a good factory model, or even one with slight modifications.
