To buy a 2007 G35X CPO'ed or not
 

Have decided to purchase a 2007 G35X. All the ones I am looking at have anywhere from 20,000 to 35,000 miles on them. Being that I am new to Infiniti's, would you pay the premium in buying a CPO or, for the most part, am I safe in not having to worry about too much going wrong?

I decided against a BMW 3 Series and an Audi a4 due to reliability concerns.

Let me know what you think. All help is much appreciated.

Thanks.

I wouldn't and didn't when I purchased mine. One of the main reasons I picked the G was for expected reliability, so paying for an extended warranty made no sense to me.
