Depends on what you want it for. If you want it as a driver and don't care about resale nothing wrong with it. If you want it for the value then that's not the right car.
Competition orange and Sonic blue probably 2 of the hottest colors in cobra world. Mystic as well but that paint job would be pricey.
It's your car do whatever you want. If your just going to sell it soon then painting it is a waste of money and you will loose money or pay for a shitty paint job.
