You can say they are just "stickers", and how expensive they are, but some things to consider.
- Make sure you are getting a very high quality vinyl decal. Many years ago I made this mistake of buying cheap material off the internet too, did not last, and did not install correctly.
- If your getting custom cut, and professionally installed, it will be the same price.
- If your buying off the net, and getting professionally installed, you might save a few hundred, and it will take your time, and be stressful to know if its getting done right.
- Doing yourself? Good for you, hopefully you have installed large decals before, very easy to wrinkle, bubble, and not get straight.
For me, I happen to like the factory ones and is well worth the price, because of the above. To each their own.
