Good question! It's very difficult to avoid ricing your car, but possible. Be creative! Don't rush on your car. Rushing on your car adds less effort and style.
How do you be creative?
Another great question! One way of being creative is making different cars out of the cars you have. For example, on your screen is a tuner R32 I made.
Another picture shows the 2015 Challenger Hellcat I made.
Another way is, use the decals from the right person. Alex53, Bartman900 are great starts. Don't use DK1221! DK1221's decals are overall overused, and I think they're a bit ricey. In my opinion, I like being different from the others and I don't use DK1221. Also, make your own decals! This one takes effort too. Don't use that pesky MS Paint. MS Paint overall isn't that good and extremely basic. Paint.NET is a great start! It's basically your basic Photoshop, best of all it's free! If you want to take decal creating to THE NEXT LEVEL, get Photoshop. Try cracking it, unless you already bought it.
