For the negligible amount of difference the top-end Challenger bests the entry-level V8 Mustang by, the price variance between the two is difficult to justify
Customer's always right, it isn't too difficult. You can save 10 or so thousand but at the end of the day if the Mustang isn't the car you want. Also, you've completely discounted the additionally enhanced components you're getting on the SRT. It ain't just engine. Brembo's, the way I hear it, don't come cheap, nor do any of the other standard amenities you're getting for your duckets.
Just a little more grist for the mill Albeeno. Since you're in the know on the 'Stang side, are they considering a fast back version? It'd be a tight homage to rework as well.
