I actually test drove an RS today (at Bill Marsh/Fred beans Ford in Newtown), and did the 'sit down' with the salesman aftrwards.
They wanted to give me $14K on my 4K mile, ordered, bought new in November '16 base FiST.
Ford does NOT offer a 0% financing deal on the "specialty cars" (FoRS, GT350/350R, Raptor, etc.) AT ALL, ANY time of the year, so you are at the mercy of the outside sources, and therefore your credit score, and how much you put down, as to what percentage you will get.
In any case, they rough figured a monthly payment for me, using a "average to good" credit score based percentage, and putting down $10K, the payments, even over 72 months, would have been about $700/month!!
It is a Nitrous Blue with the (whatever the number package) black forged wheel/PSS, moonroof, NAV, etc. package, which MSRPs for ~$43,xxx, and they were NOT gouging the price, but the customer must pay LIST.
Although I thought it was a VERY 'solid/planted' car, and did not feel that HUGE size/mass penalty over the FiST that everyone on here speaks of with this car, it does not seem to be worth over 2 times+ more than my FiST, and yes, not quite as 'tossable'.
That being said, I still would have bought it on the spot IF I had the coin (and then some, in other words WEALTHY!) on hand, even though I HATE moonroofs, and then I would have modded the ever-living crap out of it (BUILT 2.3, to 550+ AWHP, and lightened it by ~500+ lbs.!).
BTW; it DID 'ride' A LOT more firm than my FiST with 17x8s, and 215/40-17 RS-RRs on a factory suspension, but I did not notice, nor play around with the ride settings at all.
The clutch also grabbed DIRECTLY off of the floor, unlike my FiST, so that took some getting used to on the test drive.
The shifter seemed to be a shorter throw than the factory FiST's, but not as short as my Mountune plate's 30% reduction.
