Is it necessary to purchase 3 years($1000) extended warranty for 2015 ATS

[staylow]

Hi All, I decide to replace my old bmw with ATS 2015. Currently, I get two quotas from autopriceshare dealers. The first one: 2015 ATS 2.0L I4 AWD $35309.0. Second one: 2015 ATS 2.0L I4 AWD + 3 years extended warranty $36529.0.
For the first quota without warranty, I compared with other shared deals in autopriceshare.com and felt it is a decent price. However, I am not sure about the reliability of the 2015 AWD and should I pay $1000 more for the 3 years extended warranty? Thanks in advance
(In addition, this is the 'dealer warranty' rather than 'Cadillac warranty')
