oK guys I need your help again,well basically advice. I just checked out a 92 400se and it didnt work out ( price what he wanted for the car wasnt worth it) so Im going to check out a 92 s 600 tomorrow.

Quick overview, 140,000 miles, 1 owner, says its in excellent condition.
No carfax problems.

Now Im wondering what parts/services will cost more since the car is a
v-12 instead of a v-8? I know a tune up will cost more, but wont general parts be the same price?

Maybe smarten me up on the problems, or what I should know about having a s 600 instead of a s500 ?/ Thanks guys.
