Cons of buying new "used" '09?

I am planning on buying an '09 from a private person who is selling a '09 with 100 miles on it for $500 less than MRSP. He was able to get the package he wants from another dealer as his "number" came up there.
I am currently on a couple wait lists since July 9th with probably another 6 week wait at the minimum. This is a package 3 and I was on the list for a package 2 and was quoted MRSP for it. I would be paying a little more but would be getting more.
Are there any downsides of this? Will the warranty still be the same etc? Can anyone think of a reason to not so this?

There is no problem at all. All factory warranties transfer.

Sounds like a good opportunity. Might just be worth running a car fax and getting a dealer to print a service history just to make sure there is no funny business.

Doesn't sound bad, as others have said just check it out with the dealership/carfax and go for it if you can swing the slightly higher cost.

State taxes may be less. ymwv

True, however Oregon doesn't have sales tax.

I guess I dont need to know cons now because I now have a 2009 Mg Gray package 3 in my driveway! Hurray! I got it with 100 miles on it and $500 below MRSP.
I got it on Craigs list because the seller now is able to get his package 5 that he wants. I am so excited!

Congrads! Update your profile with the package #3 then.

I am now updated! 3 days and I couldn't be happier. And I have learned so much from this site! Thanks. The car seems to be all it was promised. And I saved $500. I am glad I got the bluetooth. It just might save my live.
