Understand the differences
2018 GMC C5: VIN configurations and specifications
Multiple VIN patterns can share the same trim. Compare their recorded equipment, then open a specification page for the full details.
Where these specifications come from
Specifications combine decoded VIN data, including NHTSA vPIC , with inventory records. If decoding does not identify a trim, a recorded inventory trim may be shown. VIN patterns do not confirm every installed option.
Counts describe observed VINs in our database, not factory production totals. Prices are median asking prices from qualifying U.S. listings, not original MSRP. Check the vehicle’s build sheet for exact equipment.

Do GMC C5 prices in Florida differ from the rest of the country?

6 in total, nearly all pre-owned. Counts refresh daily from live dealer inventory.
Is this the trade-in value or private-party value of my 2018 GMC C5?

To find out what a buyer or dealer would pay for your car, request an offer that takes its mileage, condition, equipment and history into account.
How we calculate these prices
We track 6 active listings for this vehicle across dealer sites in Florida, updated every day. Average and median are computed from real asking prices on live listings. We exclude the top and bottom 2% of prices to reduce the influence of extreme values. This does not verify title status or guarantee that every erroneous listing is excluded. Prices reflect dealer asking prices — not final sale prices — and exclude taxes, fees, and incentives. Trim and mileage move the price more than any other factor; see the breakdowns above.
