No...
That's by far the most outlandish question I've been asked here... whether or not there's an easy/quick way to make a car look good.
As far as I'm concerned, a good showcase car is a work of art. Works of art aren't done overnight. They take time, and care. Same goes for the cars here in ProStreet. They will take your time, and you can't make a stunning looking car after simply one day. Each car is reflection of the creator's personality, and true test of creativity. There's no set way on how to make a car look good. It all boils down to personal taste and creativity.
That there my friend, are words of wisdom.
Art = creativity and time
