2026 Acura RDX: St. Louis Pricing & Leasing Guide

The sticker, trim by trim

Five trims, one consistent gap in equipment rather than a jump in mechanical capability, and MSRPs that climb roughly $2,000–$3,000 at each step: Base at $45,100, Technology at $47,700, A-Spec at $50,700, Advance at $52,850, and A-Spec Advance at $54,850. Add Acura’s flat $1,450 destination charge to any of those and the real before-tax prices run $46,550 through $56,300. Some third-party listing sites advertise the destination-inclusive number as the headline “starting at” price, which is accurate but worth flagging so a buyer comparing quotes across two sites isn’t confused about whether both figures describe the same starting point. MSRP and destination are two separate numbers until they’re added together.

What Missouri and St. Louis County add on top

Missouri charges a 4.225% state sales tax on vehicle purchases, and local jurisdictions layer their own county and city rates on top, assessed based on where the vehicle will actually be registered. For a St. Louis County address, that combined state-plus-local rate generally falls in the high-single-digit percentage range, though the exact figure depends on the buyer’s specific municipality within the county — Frank Leta Acura’s finance office calculates the precise number due at the time of purchase rather than an estimate. One Missouri quirk worth knowing going in: the state has historically required buyers to settle vehicle sales tax at the license bureau when titling the car rather than folding it directly into the purchase at the dealership, though many dealers now collect and remit it at time of sale for financed purchases, so it’s worth confirming which process applies to a specific deal before assuming the out-the-door number at signing is the complete tax bill. Either way, Missouri taxes only the amount remaining after a trade-in credit is applied, so a fair trade appraisal reduces the taxable number along with what’s financed.

Lease or buy across five trims with an identical powertrain

Because every RDX trim shares the same 272-hp turbo engine and SH-AWD, the lease-versus-buy math comes down to how a buyer values equipment depreciation rather than any performance difference between trims. Leasing makes sense for buyers who want to step into a higher trim, A-Spec Advance for example, at a lower monthly payment than financing the full purchase price would require, and who don’t mind turning the car in every few years rather than building equity in it. Buying makes more sense for anyone planning to keep the RDX well past a typical lease term, especially on a trim like Base or Technology where the lower purchase price shortens the time it takes a loan to reach positive equity. Reviewers describe a finance process at Frank Leta Acura that moves efficiently either direction: “We test drove two, made a decision and were out the door in about 3.5 hours. Left with the new car feeling like it was a win-win,” one buyer wrote of a recent RDX purchase (Susie P.)

Financing options and the Lifetime Warranty

Frank Leta Acura backs its new-vehicle sales with a Lifetime Warranty program on top of whatever loan or lease structure a buyer chooses, and runs a Leta Loyalty program for repeat customers — both worth raising directly with the finance team rather than assuming a standard loan is the only path in, since approval terms and how each program stacks with manufacturer incentives vary by buyer and by month. A veteran- and women-owned dealership open since 1986, Frank Leta Acura has built a base of repeat RDX buyers specifically: “Wanted to say thank you to Jon Kitchen he was great to work with during my recent purchase of my RDX. Stress free experience,” one buyer wrote of the dealership’s Leta Loyalty team (Jennifer S.)

Offers move monthly

Acura sets national lease and APR programs on a roughly monthly cycle, and Frank Leta Acura layers its own specials on top, so a rate advertised this week can shift before a buyer finishes comparing all five trims. The practical approach: check current offers for what’s running today, but treat any specific advertised payment as a starting point for a conversation with the finance team rather than a locked-in number, since the final figure depends on trim, term, down payment, and trade.

Frequently asked questions

How much does a fully loaded Acura RDX cost?

The top A-Spec Advance trim starts at $54,850 MSRP, $56,300 with Acura’s $1,450 destination charge, before Missouri sales tax, title, and registration.

Is it better to lease or buy an Acura RDX?

Leasing generally lowers the monthly payment and suits buyers who want to step into a higher trim or change vehicles every few years; buying suits anyone planning to keep the RDX well past a typical loan term. Both directions are worth a direct conversation with Frank Leta Acura’s finance team given how offers shift monthly.

Does Missouri charge sales tax differently on a leased RDX?

Missouri generally taxes lease payments based on the amount financed under the lease rather than the vehicle’s full purchase price. The same combined state-and-local rate applies either way, based on the vehicle’s registration address; what differs is the amount that rate gets applied to.

Can I lease a 2026 RDX at Frank Leta Acura?

Yes, Acura offers lease programs across the RDX lineup. Current terms move monthly with Acura’s national programs, so the finance office at Frank Leta Acura is the source for an up-to-date quote on a specific trim.

Trade value, down payment, term length, and which of the five trims a buyer settles on all move the final number more than any generic online calculator can predict.
