Carmax sells Porsche warrantee

[baxster]

I did a forum search on Carmax and didn't see anything like this.

I test drove a nice 04 S today at carmax. It has 43k miles for $22600. The sales guy say I can get an extended warrantee through carmax from PORSCHE. He says a bumper to bumper 125,000 total mile (that would give me 82,000 miles), 6 year warrantee would cost $2500.

Has anyone heard of Carmax selling a Porsche warrantee? Does this sound like a good deal? As for the car, Kelly's says it's a fair private party price.
