2. Make sure you pick the right orientation to print the parts. Typically the bottom layer looks better than the top most layer, assuming you have a level bed, PEI bed, etc..
3. Look up the Ironing feature in Cura slicer software as another alternative for a nice top layer
4. There's a big difference between the ABS process used by car manufacturers and the many ABS filaments used for 3d printing. Although most of them do have a higher temperature rating than other materials, make sure you pick the right ABS recipe filament because some do have additives which change some properties.
4. If you're sticking with one ABS color, you can also apply a heat resistance coating, and also a chrome,gold, metallic,etc final coating of paint.

Thanks for the tips.
1. I have done acetone smoothing and I don't like it. It takes away too much detail. I use a 3d print coating that I can color to get the desired finish. After it cures I can wetsand and polish it if I even need.
2. This was just a quick idea I threw up to generate interest. I will show some "finished" pieces very soon. Only time I have warping issues is when I print without a brim.
3. You are completely right with the bottom layer looking the best. I have tried some prints upside down and they do come out really good.
4. Absolutely right that manufacturers use different techniques to produce ABS parts (mostly injection or press molding) compared to additive manufacturing that is used here. But, nonetheless, its still ABS plastic and has a higher extrusion temperature then most other materials so it will not just melt off of your car.
