I'm shopping for a '10 or '11 RX 450h with 20-50k miles but wondering what the additional dollar value of a CPO from a dealer is compared to a comparable non-CPO/private party car. If I felt the need for extended warranties (and I'm not 100% sure they're worth it), a trustworthy 3rd party contract would range from $2k and higher. Is a CPO's value similar?

As a 9k/year driver, I expect I'd have another 6-18 mos of factory basic bumper-to-bumper left on any car in that year range, as well as 24-36 mos of orig powertrain and 48-60 mo of hybrid system coverage.

Mechanically, it seems a CPO might be a near wash if a non-CPO price was low enough. But are there expensive (i.e. $1000+) non-power train or hybrid items (like Nav system, power controls, etc.) I should be worried about that might go after the basic warranty expires?

Am I wrong or missing something? Thoughts?

Thanks.
