Besides tires, another thing I've never seen pop up in an automotive rendering is the car's underside. Few consumers that aren't mechanics will ever see the underside of their own car, and thus it doesn't need any design.
That may change. The UK has seen an uptick in what they call "cat (catalytic converter) theft," particularly from SUVs and delivery vans, whose high stance makes the theft easy:
These thieves are not sophisticated. Any vehicle with ground clearance can have the catalytic converter ripped off within seconds, according to the police, as they typically use plumber's pipe cutters or a cordless saw to slice through the exhaust and supports....Cats are mainly being stolen for their precious metal value—if properly recycled they can be worth between £50 and £100.
While the thief stands to make 100 pounds at most, it can cost more than 2000 pounds to repair the damage, which has fleet owners particularly worried. When you own dozens of trucks with enticingly high ground clearances, cat theft costs can skyrocket. And while the problem is just now seeing an uptick in the UK, it's been a problem Stateside for years.
