Presented as a sales-training hypothesis, not a verified demographic fact.

“You love the premium feel of the GMC Sierra AT4 — how would you feel if it had 700 supercharged horsepower and the aggressive stance to back it up?”
Present Premium Performance With Confidence.

Example Opening Presentation
“For years, if a customer wanted a 700-horsepower factory supertruck, they had to leave the GM showroom for a TRX or Raptor R. The Hennessey Goliath 700 changes that entirely: seven hundred supercharged horsepower out of the 6.2L V8, Multimatic DSSV suspension, steel Goliath bumpers, and genuine off-road capability — all backed by a 3-year, 36,000-mile warranty. Let me show you what makes this truck so special.”
Common Objections
“Why pay this much over a stock vehicle?”
Frame it as a hand-built, limited-production machine — not an upcharge on a truck, but an engineered, warrantied product with its own performance, exclusivity, and story.
“I could build something like this cheaper at a local shop.”
Hennessey upgrades are engineered, installed, dyno-tuned, and warrantied as a complete package. The value is the integration, the reputation, and the warranty — not a parts list.
“Is it still reliable as a daily driver?”
Walk through the warranty and the engineering discipline behind the build. Position it as performance you can live with every day, not a weekend-only toy. Never promise reliability beyond what the warranty states.
Closing Conversation
“If you want the luxury of a GMC Sierra with the power and presence of a true 700-horsepower supertruck, the Goliath 700 is the machine. Let's see how we can secure your build.”
