Custom Sprinter Vans for Sale: What to Look For Before You Buy

Custom Sprinter vans available now

First Class Customs holds finished and near-finished vehicles for immediate sale at its Springfield, Missouri facility, and what is listed changes weekly. Every vehicle is published with its stock number, model line, rear seating and chassis.

Inventory changes weekly. The full list, with the build specification for each vehicle, is on the inventory page. If nothing listed matches what you need, a custom build to your specification is the alternative.

What you are actually buying

A custom Sprinter van for sale is a finished conversion. It reaches the market by one of three routes, and the route changes what you are buying.

A custom Sprinter van reaches the market as an unsold factory build, a factory demonstrator or a pre-owned vehicle. Check the warranty position and who built it.

New build, inventory or pre-owned?

A new build gives full warranty and full specification control. Inventory is fastest. On a pre-owned vehicle the First Class Customs conversion warranty does not transfer.

The First Class Customs conversion warranty covers the original purchaser only. It does not transfer to a subsequent owner. The term is three years or 36,000 miles from the original purchase date, with a separate one year term on audio components, and all warranty service requires pre-authorisation before work begins.

So if you are buying a used First Class Customs vehicle, budget on the conversion being out of warranty regardless of its age or mileage. That is not a reason not to buy one. It is a reason to price it correctly and to inspect it properly.

The Mercedes-Benz chassis is warranted separately by Mercedes-Benz, which First Class Customs documents as a 3 year or 36,000 mile new vehicle limited warranty, a 5 year or 100,000 mile powertrain limited warranty and a 5 year or 100,000 mile federal diesel emissions warranty. Those follow Mercedes-Benz's own transfer terms, which are not the same as the conversion warranty's. Full detail is on the warranty page.

A 10-point checklist before you buy

Work through these in order. The first four will disqualify most of what is listed badly.

1. Who actually built it? Not who is selling it. Get the manufacturer's name and check they still exist. A conversion from a shop that has closed is a conversion nobody will service.
   
2. Was the work done in house or subcontracted? Metal fabrication, electrical, upholstery, cabinetry. A vehicle where all four were done under one roof has one party accountable for the result. First Class Customs does all four on site at its 30,000 square foot Springfield, Missouri facility.
   
3. Is there a written conversion warranty, and does it transfer? Ask for the document, not a summary. Assume it does not transfer unless the document says it does.
   
4. Is the electrical work documented? Circuit by circuit, with cable sizes. This is the single best proxy for build quality, because the shops that document electrical work tend to do everything else properly too.
   
5. What is the chassis designation and the mileage? A 3500 XD, a 170 Extended and a 144 are different vehicles with different capacities. Know which one you are looking at.
   
6. Is there a Manufacturer's Statement of Origin? For a new build this is the document that gets the vehicle titled. First Class Customs provides it and coordinates title and registration paperwork with your local titling authority.
   
7. What is the seating arrangement, and how is it mounted? Seat mounting is structural work. Ask to see how the seats attach to the floor.
   
8. What exactly is included in the price? Delivery, title work, any remaining warranty, and whether the specification sheet you were shown matches the vehicle in front of you.
   
9. How does it get to you? First Class Customs delivers by enclosed transport from Springfield, Missouri to any address in the United States, or you collect in person at the facility.
   
10. Who services it afterwards? The company that built it, or nobody. For complex warranty repairs a First Class Customs vehicle returns to the Springfield facility, and the owner bears the transport cost to the warranty service location.

What custom Sprinter vans sell for

Pricing in this market is by specification, not by trim level, which is why so few manufacturers publish a number. The four drivers, in order of weight, are the seating, the privacy divider and layout, the technology package and the interior finish.

For pre-owned vehicles, price reflects mileage, age, the original build specification and the remaining warranty term, rather than a flat percentage off new. A high specification vehicle with high mileage and no transferable conversion warranty is a different proposition from a low mileage demonstrator, even if the model line is identical.

One thing that is not in a factory-direct price: a dealer margin. Builds are ordered from the people who make them.

Financing is arranged through qualified lending partners for both new builds and inventory purchases, and the Mercedes-Benz chassis and the conversion can be financed together in a single loan, which is the standard structure. Detail is on the financing page.

Where to buy a custom Sprinter van

Four routes, and they are not equivalent.

Factory-direct from the manufacturer. You buy from the company that built the vehicle. The specification sheet comes from the people who wrote it, the warranty comes from the people who did the work, and you can visit the facility. First Class Customs sells this way from Springfield, Missouri.

A dealer. Fast, and often the only route to a specific used vehicle, but the seller did not build it. Questions about why a system was specified a certain way usually cannot be answered.

A broker. Useful for finding a vehicle across several sources. Be clear on who carries the recourse if something is wrong, because it is frequently nobody.

Private sale. Lowest price, no recourse at all, and no conversion warranty. Only sensible with an independent inspection and a verified build history.

How much is a custom Sprinter van?

First Class Customs prices by specification rather than by trim level. The largest cost drivers are the seating, the privacy divider and layout, the technology package and the interior finish.

Does the conversion warranty transfer to a second owner?

No. The First Class Customs conversion warranty covers the original purchaser only and does not transfer to a subsequent owner.

Yes. First Class Customs arranges financing through qualified lending partners for both new custom builds and inventory purchases. The Mercedes-Benz chassis and the conversion can be financed together in a single loan, which is the standard structure for these purchases.
