Correct, the $160 was for the DCCV.
I happen to have a DATC in the garage that I bought off eBay as a spare. The wife recently traded in her 2002 LS for a 2010 MKZ so it's just sitting there.... I think the DATC is different between 2002 and 2003 unfortunately, especially if you have heated and cooled seats.
