SPF or GT500KR

[STL Mark]

Keep the SPF, get the KR - drive it for a year or so, and if you start to feel the financial pinch - sell the KR - It should hold much of it's value for a year or so. In a way, you'll be driving the Mustang for FREE!. Since prices for these cars will be well above MSRP for quite some time (and since you said you'll be able to get your KR at MSRP).

As a reference - take a look at Z06's. Their MSRP was around 65K when the C-6's came out. Most dealers sold them at 10K or 15K over MSRP - and there was a waiting list to buy! Now that same 2006 Z06 with low miles can be had on the used market for 60K. In effect - if those owners bought their car new in 2006 (at 10K over MSRP) then drove it for a year and now sells it for 60k - they paid 15 thousand dollars for 1 year of driving (plus taxes and insurance).

But if you can actually get the KR at MSRP - you should be able to unload it (if you have to) for the next couple of years at close to the MSRP - in effect driving it for free! I know it's a little twisted - but these cars will be selling well above MSRP for the first 2 years for sure.

Besides - no matter what happens - you can still pull up to the Ford dealership in your SPF and drive them all crazy!
