Ford / FPV 2.9% finance

[FPV414]

What's the catch with the 2.9% finance Ford / FPV are offering at the moment?

If you go on the FPV site it says you can buy a brand new or demo F6 @ $54,990 driveaway on the 2.9% "comparison" rate, with a 60 month term.

What would this end up costing over that amount of time, out of interest?

I hear that with this kind of finance deal, further negotiation isn't really allowed, large deposits aren't allowed and early payment fees and account fees are high.

Sorry for the noob questions - never really looked in to financing a car before.. thought someone here may have bought a car using this deal in last year's sale.
