Should You Buy a 2026 or 2027 GMC Sierra 2500HD in Houston?

Buy a 2026 GMC Sierra 2500HD if you want a heavy-duty truck you can price, test drive and finance now. Wait for the 2027 if its published towing and powertrain figures fit your load better.

What does a 2026 or 2027 Sierra 2500HD cost at Group 1 Buick GMC North?

Your cost is the price of the truck plus Texas tax and registration. For 2026, GMC prices the Sierra HD from $47,000 for the Pro to $94,200 for the Denali Ultimate. Texas motor vehicle sales tax is 6.25% of the sales price, minus any trade-in allowance (Texas Comptroller of Public Accounts, 2026).

On a 2026 SLT at its $65,200 starting MSRP, 6.25% tax with no trade-in comes to $4,075. A trade-in allowance lowers the taxable amount, so the tax falls with it.

Registration is a separate charge, and it depends on the truck’s gross vehicle weight.

Add the tax and registration to the price of the truck you pick. That gives you a full cost to compare against the other model year.

When is a 2026 or a 2027 Sierra 2500HD the wrong choice for you?

A 2026 is the wrong choice if the 2027 figures fit your load and you can wait for that truck. A 2027 is the wrong choice if you need a truck now, because the 2026 is the one you can price, test drive and finance today.

If you would rather not buy outright, we offer Buick and GMC leases, typically 2 to 3 years. At lease end, you can turn the truck in, buy it out, or extend the lease. We also make lease buyout offers.

A lease suits a buyer who expects to change trucks in a few years. A buyer who plans to keep one truck for a long time will usually compare that against a loan.
