Here are the prices I paid at the dealer. I know I could get the coils for $5-6 dollars less each but it was worth the extra for the convenience to get everything down the street. Also for $6.82 it was worth getting the jetta taillight connectors from the dealer.

coils 5@$30.66
coil plug 4B0-973-724 5@$14.27
WIRES 000-979-133-A 10@$5.37
little red seal 25@$.60
cap 6X0-971-921-A 5@$3.69
wire set 000-979-134 3@$5.37
jetta connector 2@$6.82

Plus tax the total is $358.64. I don't know if the dealer is much cheaper where you live but these are the prices at my dealer. You'll note that a the 3 wire sets at $5.37 each were not priced on your list. I'm happy with the purchase and cant wait to put it in but where is the price discrepency? Is it just between the dealers?

between dealers. You gotta watch eBay for coils...i picked up 4 for $45 shipped plus one at the dealer for $25. that's half price on coils.

I get your before tax total to be US$341.55. My before tax total was equivalent of $246.89 at current exchange rates. US$94.66 less. I get a 20% to 30% discount off list from Kris at VM Autohaus and it obviously helps.
