Around Concord, the Sierra 1500 lease market splits cleanly in two. Car Thrive checked the specials pages of six New Hampshire and northern Massachusetts GMC dealers plus GMC's own offers on October 10, 2026. The cheap headlines — $279 to $299 a month — are all on the entry Elevation trim, and nearly all of them require you to already lease a GM vehicle. Step up to the better-equipped SLT Crew Cab, the truck most Sierra shoppers actually price out, and there are exactly two published leases in the area: Tulley Buick GMC at $699 a month, and Quirk Buick GMC of Manchester at $430. That gap is the story of this market in October.

GMC's featured factory lease for the Concord area (ZIP 03301)
Read the fine print before comparing payments. Almost every low headline in this market carries a loyalty string: Banks' $279 and $365 are for current lessees only, GMC's lowest due-at-signing figures are for current GM lessees (and its $199 variant is employees only), and Quirk's $430 bakes in a trade-in allowance rebate for a 2012-or-newer trade plus a requirement that your household already leases a Buick or GMC through GM Financial. Quirk's offer also contradicts itself — the headline says 24 months, the disclaimer says 36. Get whichever term is real in writing before you sign anything, at any store.

Not publishing a Sierra 1500 lease this month: DiPrizio GMC Trucks in Middleton and Fairfield's Cadillac Buick GMC in Keene list no Sierra lease at all, and Greater Lowell Buick GMC's only Sierra lease page dates from May 2019. GMC also advertises a $199-a-month variant of its featured lease — for GM employees with a current eligible lease only — so it is not in the table.
Ratings alongside price
Checked October 9, 2026: Banks is rated 4.6 stars on Google from 4,894 reviews, Tulley Buick GMC 4.6 from 1,084, Key GMC of Rochester 4.6 from 809, and Quirk Buick GMC of Manchester 4.5 from 957 — a tight pack, with Quirk in the middle of it. Ratings do not separate these stores much; the offers do.
The bottom line for October: if an Elevation work truck does the job and you already lease a GM vehicle, Banks' $279 a month in Concord is the number to beat, and GMC's $299 factory lease is the fallback if it is not. But if you want the Sierra most buyers actually take home — the SLT Crew Cab with the V8 — Quirk Buick GMC of Manchester is the best deal in the Concord area this month, and it is not close: $430 a month with $2,700 down, against $699 a month and $5,694 due for the same trim at Tulley. Just get Quirk's term — 24 or 36 months — confirmed in writing, because its own page says both.
