Hi,
I have an 07 335 coupe . The car is certified till the end of April.
Im thinking about getting an extended warranty i contacted Mercury,GMPP,Ford,Carchex and Warranty Direct.
The best quotes i got was National Platinum for 3500 $4 years It covers nav and a lot of electrical but it is lacking in the mechanical department.
AUL have a contract for 4 years 4000$ it covers a lot of mechanical but no nav and no supporting many of the electrical stuff.
What do you guys think i should go with?
i am still debating if i should get an extended warranty considering that i am looking into tuning my car and upgrading the turbos.
