The nose cone kind of looks too short, and the wind doesn't look right too. The joint of it with the body was much smoother in original ones, plus proportions are kind of strange. The badge behind the rear window is not the script "Charger" one the daytonas had. Could have been repainted, so i guess this doesn't count, but the stripes/Daytona badge look nothing like the original one's
In the case of this car, it just looks plain weird. Most probably the fault of an amateur installing rather than being badly made itself. Compare it to a photo of a real Daytona.
