Try this formula

parts $1151.71 (from http://www.x3world.com/showarticle-249.html) + these parts
CENTRAL INFORMATION DISPLAY SCHWARZ 1 10/2004 65503417417
-- CENTRAL INFORMATION DISPLAY GRAU 1 10/2004 65503417418

I’m guessing another $1000. for these part = $2151.71 + 2151.71 (labor ) = $4303.42 + tax

looking for a better guestimante
