Despite the adversity and contentiousness being levied against you here, I believe (that) your goal is to extricate yourself from the financial burden of this truck in it's current condition.....
I have no idea why some here (seem to) consider it good form to respond to you in this way....
But, in order to get out of this financial snafu unscathed, I still feel that the dealer is responsible to have sold you only a new vehicle according to the purchase agreement...............
This means that they are compelled (under the terms) to do what the agreement states...... PERIOD.
They can either refund your money or give you a new SRT-10 truck.... If that is possible.
If not, then you get an attorney.....
