SUVs and trucks have ~25–35% more surface area than a sedan, which translates to more wash, decontamination, and paint-correction time. Interiors also have a third row, more carpet square footage, and more glass. The price difference reflects the actual additional time on the vehicle.
On Maximum's pricing, SUV/truck rates are $50–$55 above the sedan price across all three packages. Oversized vehicles (extended-cab pickups, large SUVs like a Suburban or Expedition) may add another tier — we'll quote it specifically when you call.
There's no hidden upcharge. The sedan price you see is the sedan price; the SUV/truck price is the SUV/truck price. No surprises at the end.
