If you would like some new 16in steel wheels, in 16x7 et 37 size which
fit Vanagons without spacers as long as you don't go overboard on tire
size, I'll tell you where to find them as long as you keep it a
secret, OK? ;-). We do not want some pricey vendor to find out, buy
the whole stock and resell them for 10 times the price (GoWesty).

Go to tirerack.com and search for wheels for a 99 Merc C230.  Click on
the 'Steel Wheels' tab in the search results.  Yeah - $15!  It's
Christmas, baby!

This has been discussed on the Samba, so you can find more info there.
