Do I need to buy an additional extended warraty (8yr/100000mi) for a certified toyota camry (23000mi/2008yr)?

I bought a used certified toyota camry (2008/23000mi)from a dealer. The dealer forced me to buy an extended warranty (8yr/100000mi) warranty at $1550. I still have a warranty for a toyota certified vehicle (1year/12000 comprehensive, 7yr/100000mi power train, 1year road side assistance). Do you think I need to buy an extended warranty?
