Many will opt to get a custom wrap because the steel could get scratched and start rusting, plus they are buying for clout and are now in too deep to stop throwing money away on making it “look” better.
Some have also opted into getting a third party service to chemically deposit a layer of gold on the surface of the steel. Making it an even bigger money sink for little benefit and basically not worth driving around almost at all except for showing off.
For durability and smallest features, a metal unibody types that don’t have seams are great.
For performance, I opt to have an nvme SATA enclosure that is USB 3.1 capable. Copying 15 GB in a minute or 2 is so satisfying. Plus my god being able to easily change the nvme SATA drive on the fly if needed and it being able to go up to a few TB without loss of performance is just to good
For price, nothing beats free. Just don’t expect much more than what you get.
