about the maintance program?

brickturtle

well today i picked up my z
and im super happpyyy

thee question is that when i was talking to the financial manager
at the end to sign couple papers, he was trying to get me to buy the maintance program thing,...
First he mentioned my warranty would be voided if i didnt follow certain routine and

Second also mentinoed that 370z only takes special engine oil which would cost 100 bucks outside but they have a flate rate or something

Third, he said that 370z will cause problems and warranty would be voided
if i would do regular synthetic oil changes at like jiffy lubes..

he said he would add 38 dollars to the monthly payment untill the lease would end would cost about 1120 dollars.

im wondering if this is a fair deal
and what he claimed was true
it sounded like a hell of a deal but i reallly dont want to spend
extra on something that i dont really need since im already on a
tight budget

so help me out guys@
