What a Mercedes-Benz C-Class costs in Austin: C 300, C 300 4MATIC®, AMG® C 43 and AMG® C 63 compared
If you ask what a C-Class costs in Austin, most answers hand you one number, as if every trim and every lot priced alike. They don’t. The trim sets the sticker, new or certified pre-owned sets the next step, and Texas fees follow written rules that stay the same whichever trim you pick. For a shopper in Buda, Kyle or Dripping Springs, that makes the choice smaller than it looks.
Keep reading below, then schedule a test drive in Austin. Bringing your own numbers to the lot settles this faster than any spec sheet.
What does a new Mercedes-Benz C-Class cost in Austin?
A new C-Class costs an Austin buyer the maker’s starting MSRP for the trim, and the 2026 range runs from $49,650 for the C 300 to $88,000 for the AMG® C 63. Mercedes-Benz of South Austin sells the new C-Class, along with the rest of the lineup from the CLA to the G-Class.
| 2026 trim | Starting MSRP | Horsepower |
|---|---|---|
| C 300 Sedan | $49,650 | 255 hp |
| C 300 4MATIC® Sedan | $51,650 | 255 hp |
| Mercedes-AMG® C 43 Sedan | $64,150 | 416 hp |
| Mercedes-AMG® C 63 S E PERFORMANCE Sedan | $88,000 | 671 hp |
The Austin commute is a C 300 job at 29 mpg and $49,650
For a buyer who drives Austin streets and I-35 every day, the C 300 is the answer. It lists at $49,650, makes 255 hp, and earns an EPA combined rating of 29 mpg, the highest in the C-Class line.
The mean travel time to work for Austin city workers is 24.2 minutes, according to the U.S. Census Bureau’s 2024 American Community Survey 1-year estimates. A commute that repeats every weekday rewards the lowest running cost the line offers, and the C 300 has it.
The AMG® C 43 is rated at 22 mpg combined, which is seven fewer miles from every gallon. For a driver whose week is mostly the same commute, that gap shows up at the pump every time.
The C 300 also gives up very little in everyday terms. Its 255 hp is the same figure the C 300 4MATIC® carries, and its 11.6 cubic feet of cargo space matches every other C-Class trim. If your Austin week is work, errands and the occasional dinner across town, the C 300 covers all of it at the lowest price on the lineup.
Austin buyers who want 4MATIC® pay $2,000 and give up 2 mpg
The C 300 4MATIC® lists at $51,650, which is $2,000 over the C 300. Its EPA combined rating is 27 mpg against 29 for the C 300, and its horsepower is the same 255.
That makes this the cleanest decision in the whole lineup. The engine output does not change. The cargo space does not change. What you buy for the extra $2,000 is the 4MATIC® system itself, and what you give up is two miles per gallon on every tank.
So the question for an Austin buyer is whether you want 4MATIC® on your car. If you do, the price of getting it is small next to the gaps higher in the line. The step from the C 300 4MATIC® to the AMG® C 43 is $12,500.
If you do not have a reason to want it, the C 300 is the better value. You keep the $2,000 and the better mileage.
A family in Austin gets the same 36 inches of rear legroom on every trim
The C-Class has 36 inches of second-row legroom and 11.6 cubic feet of maximum cargo space, and those figures do not change from the C 300 to the AMG® C 63. For a family, that settles something important: the trim you choose has nothing to do with how much room you get.
That should shape how a household spends its money. If your Austin family has decided on the C-Class, the $38,350 spread between the cheapest and most expensive trim buys no extra space at all. It buys power and a different kind of drive. A family that needs room above all should put its budget into the C 300 or the C 300 4MATIC® and keep the difference.
It also tells you where the C-Class stops. A household that needs more than 36 inches in the second row, or more than 11.6 cubic feet behind it, has outgrown the sedan. Mercedes-Benz of South Austin sells the GLC, the E-Class and the GLE as the next sizes up.
What does an AMG® C 43 or AMG® C 63 cost against a C 300?
The AMG® C 43 starts at $64,150 and the AMG® C 63 S E PERFORMANCE at $88,000, against $49,650 for the C 300. Power climbs with the price: 416 hp and 369 lb-ft in the C 43, 671 hp and 752 lb-ft in the C 63, and 255 hp and 295 lb-ft in the C 300.
The C 43 also carries an EPA certification of 19 city, 27 highway and 22 combined mpg, where the C 300 earns 29 combined. That is the running-cost side of the price. A buyer who wants the power pays for it at the pump as well as at signing, and gets the same 36 inches of rear legroom either way.
Mercedes-Benz of South Austin calls itself a Mercedes-Benz AMG® Performance Center. If power is the reason you are shopping, start with the C 43 and see whether the C 63 is the car you came for.
How does a certified pre-owned C-Class price compare with a new one?
A certified pre-owned C-Class sits below a new one on price, and Mercedes-Benz of South Austin sells both new and certified pre-owned Mercedes-Benz. Eligibility for the certified program, set by the maker’s criteria, shapes which cars qualify and what they cost.
To qualify, a vehicle must be a model 6 years or newer with less than 75,000 miles and pass a 165+ point inspection, according to Mercedes-Benz USA (2026). The Certified Pre-Owned Limited Warranty then adds 12 months of coverage with unlimited miles.
Cost is the reason to run this comparison before you pick a trim. In Cox Automotive’s 2025 Car Buyer Journey Study, 62% of vehicle buyers said leasing or owning a car is too costly. A certified car also changes the tax math: Texas’s standard presumptive value rule for used vehicles does not apply to vehicles sold by dealers (Texas Comptroller of Public Accounts, 2026).
What do Texas fees add to a C-Class price in Austin?
Texas sets the sales tax, title and registration charges by rule, and the same rules apply to every C-Class trim. Sales tax is 6.25% of the sales price minus any trade-in allowance (Texas Comptroller of Public Accounts, 2026), so it rises with the trim, while the registration lines below stay put.
| Charge | What Texas sets | Source |
|---|---|---|
| Registration | $50.75 base plus $1 for TexasSure, shown as $51.75 | TxDMV, 2026 |
| Travis County local fee | $11.50, under the $31.50 the statute allows | TxDMV fee chart, effective January 1, 2026 |
| Dealer documentary fee | No hard dollar cap; filing with the state required above $225 | OCCC Bulletin B16-5, 2024 |
Under that bulletin, a seller does not have to give the state a notification or cost analysis before charging a documentary fee of $225 or less. Above $225, it must provide both.
A vehicle inventory tax line is a different matter. It is a property tax assessed on the dealer, not the buyer, and a negotiable item on the sales agreement, and sales tax is not charged on it (Texas Comptroller, Motor Vehicle Tax Guide, 2026).

Frequently asked questions
Does the C-Class price include tax, title and fees?
No. The maker’s starting MSRP is the price of the car, and Texas sales tax, title and registration come on top, as set out above. The title fee is $33 for a Travis County resident (Texas Department of Motor Vehicles, Motor Vehicle Title Manual, August 2026).
Does Mercedes-Benz of South Austin offer financing and leasing specials?
Yes. We offer both financing specials and leasing specials. There is also a secure finance application online.
What should I ask for on a C-Class quote at any dealer?
Ask for every line in writing: sales tax, title, registration and any documentary fee or vehicle inventory tax. Texas charges an electric-vehicle fee of $200 a year, but TxDMV states it does not apply to hybrid vehicles (Texas Department of Motor Vehicles, 2026). The EPA lists the C 300, C 300 4MATIC® and AMG® C 43 with hybrid powertrains.
How long is the basic warranty on a new C-Class?
The basic warranty on the 2026 C-Class is 4 years or 50,000 miles, according to Mercedes-Benz’s Model Year 2026 warranty booklet. It covers the whole C-Class line, so it does not change with the trim.
Did the C-Class earn a safety award?
Yes. The Insurance Institute for Highway Safety gave the 2026 C-Class 4-door sedan a 2026 TOP SAFETY PICK in midsize luxury cars (IIHS, 2026).
