So we went and looked at some cars today and I am having trouble answering a couple of questions. At what point should you add CPO cars into the mix with new cars? For instance, most VWs might as well be purchased new since they are usually in the $20K to low 30s but at what point does CPO make sense? If buying CPO, what are the miles worth? For instance, Car A is $50K brand new, but CPO with 20K miles, what discount makes sense for that CPO car? Annual payments * mileage driven per year = Discount? Example: PMT of $500/mo or $6K/year and 10,000 miles per year so $12K discount? A $500/mo car payment is just an estimate. Maintenance isn't really a decision point unless it needs some horribly expensive service early in its life.
To me it really comes down to what you are really after and the particular brand's CPO program. Some CPOs offer almost nothing over used (some give you maintenance and new car financing). I don't think I'd ever buy a new car: if I'm going new, I would probably stick to a lease (which is what I did with my VW).
The other thing is I've noticed CPO cars that are almost the same price as brand new. Is a shorter warranty worth $1k? What if it is $5 or $6k?
My next car will probably be a CPO, but who knows.
