I got the regular full service car wash yesterday. For $25 they clean the exterior and then wipe down and vacuum the interior surfaces and carpet. And they also clean your mats too (but they don't shampoo the carpets or seats). The mats and trunk were a bit wet afterwards but I guess that's what you get in a ten-minute cleaning service -- and it beats having to do it yourself. The car had the clean smell afterwards and it was pretty well cleaned (the trunk could have been wiped clean a bit more thoroughly but it was good enough). Next time I'll press the button to get the underside cleaning during the exterior car wash.
