Custom Order Your Perfect GMC Sierra

Never settle for a truck that is "close enough." If you need a specific bed length, a distinct interior trim, or the maximum trailering package for your business, ordering direct from the factory is the smartest way to buy. Build your exact GMC Sierra with no compromises.

How long does a custom truck order take?

A custom factory order for a GMC Sierra typically takes 8 to 12 weeks from the date the order is accepted by General Motors to the moment it arrives at our Mahwah dealership. Timelines can vary based on trim levels, engine availability (like the Duramax diesel), and specialized technology packages.

How to Custom Order a GMC Sierra in NJ

Ordering a vehicle through Buick GMC of Mahwah is a straightforward, transparent process designed to give you total control over your truck's specifications. Here is how it works:

1

Design Your Build

Select your preferred trim, engine configuration, cab size, bed length, and paint color. Decide which packages—like the Max Trailering Package or Denali Reserve Package—fit your lifestyle.

2

Submit for Allocation

Our ordering specialists review your build, confirm pricing, and match it to our dealership's factory allocation. We then submit the final design directly to General Motors.

3

Track Production

Once GM accepts the order, you will receive a tracking number. We provide regular updates as your truck moves down the assembly line and is loaded for transport to New Jersey.

4

Delivery & Financing

When the truck arrives, we perform a comprehensive PDI (Pre-Delivery Inspection). You sign the final paperwork, lock in your financing or lease terms, and take the keys.

Should You Custom Order or Buy Off the Lot?

Not sure if ordering is right for you? Use this simple framework to decide your best path forward in the current market.

Why Custom Order?

  • You want a specific feature combination (e.g., AT4 with the Duramax and CarbonPro bed).
  • You are buying a commercial truck and need specific payload margins.
  • Your current lease ends in 3–4 months, and you can afford to wait.

Why Buy Off the Lot?

  • Your current vehicle is damaged or broken down, requiring immediate replacement.
  • You want to take advantage of aggressive end-of-month inventory incentives.
  • You are flexible on paint color or minor package details.

Frequently Asked Questions

Does a custom order cost more than buying inventory?

No. You pay the exact MSRP for the truck and the packages you select. In many cases, custom ordering saves you money because you are not paying for dealer-installed accessories or optional packages you didn't want in the first place.

Can I lock in my financing or lease rate when I order?

Rates are typically locked in at the time of delivery, but General Motors frequently offers incentive protection programs. This means you get either the incentive available when you placed the order OR the incentive available when the truck arrives—whichever is better for you.

Is a deposit required to order a GMC Sierra?

Yes, a modest, refundable deposit is standard practice to secure the factory allocation and place the order in your name. Our specialists will review the specific deposit amount when finalizing your build.
