1. That motor is a low speed motor, as such it is massive. It weighs 3044 pounds. The Tesla motor runs at nearly 10 times the speed, and ought to be roughly a factor of 10 lighter. 2. See how the price drops by almost 10% when you buy more than 5 of these motors? Now imagine you are buying 20,000+... 3. You can bet the manufacturer of the motor (Baldor) did not get $25k for it. I imagine the markup for the reseller is of the order of 30-50%, on top of other costs such as transport. These do not apply to Tesla.
I am pretty sure even $6000/unit is an over-estimate.
I have some information from an occasionally reliable source that the entire car costs around $20,000 to make. This is the "incremental cost", after tooling, R&D etc has been paid for. This is apparently about the same as a top level mass produced luxury Benz - for the Benz, the much higher inherent production cost is offset by the scale and efficiency of their production line.

That $20k motor is much less advanced than what's in a Tesla... So @ $24k I think its a bargin... what is the rest of the car? Aluminum and Plastic and a couple of computers...
General Purpose 350HP motor. $25K http://www.globalindustrial.com/p/motors/ac-motors-2-phase/3...
In general these motors have tight tolerances and aren't the motors in your electric shaver
The entire car cost $70K...
