How much does the 2020 BMW M4 cost?

Prices are up 2.60% year-over-year — a sign of continued demand for this model year.

There are 153 listings available, which gives you a modest amount of inventory to compare before you buy.

Is the 2020 BMW M4 a good car?

Yes — 5/5. The 2020 BMW M4 is the last year of the first-generation car, and it follows BMW M’s familiar formula of turning the 4 Series coupe into a sharper, more aggressive performance machine. It is a two-door-only model, which keeps the focus on coupe and convertible performance rather than everyday practicality. Under the hood, it uses a twin-turbo 3.0-litre inline-six with 425 horsepower and 406 lb-ft of torque, and BMW pairs that with rear-wheel drive plus either a six-speed manual or seven-speed automatic transmission. Standard equipment is generous for the class, and the car includes leather upholstery, climate control, LED headlights, and 18-inch alloy wheels.

32.0% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2020 BMW M4 reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The 2020 BMW M4 is built around motorsport-derived hardware such as an Active M Differential, standard M compound brakes, and available Adaptive M Suspension, which supports its performance-focused reputation. At the same time, this is still a high-end performance car that may have been driven hard, so you should expect wear to show up first in the brakes, suspension, steering, and any aftermarket modifications.

For used buyers, the main long-term ownership risk is paying for deferred maintenance or hard-use wear that may not be obvious at first glance.

What should I look for when buying a used 2020 BMW M4?

At 71.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any prior damage, title issues, or repeated repairs show up in the record. Put inspection priority on the brakes, suspension, steering, and signs of aftermarket modifications, since those are the areas most likely to reflect hard use. Focus on overall condition consistency, because a performance car can look clean while still carrying expensive wear underneath.

Is now a good time to buy a used 2020 BMW M4?

This looks like a moderate, selective buyer’s market, so you can shop patiently and still find worthwhile options.

• Deal availability: 32.0% of listings are priced as good or great deals.
• Inventory: There are 153 listings available.
• Price trend: Prices are up 2.60% year-over-year.
• Clean inventory: 71.2% of listings are accident-free.

If you find a listing below $49,868, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 BMW M4's resale value?

The current average of $56,516 sits slightly above last year's $55,086.

That upward move suggests the market has held value reasonably well for this model year, which can help if you plan to sell later. The fact that prices are still tracking above the prior-year average also points to steady buyer interest rather than a softening market. For a future seller, that means a well-kept example with clean history and strong presentation should remain easier to position competitively.

Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2020 BMW M4 or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 32.0% of listings are priced as good or great deals.
• At 71.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices are up 2.60% year-over-year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2021 if:

• At $64,365, the 2021 costs more than the current year's $56,516 average.
• It emphasizes driving enjoyment while adding a more comfort- and practicality-limited setup.

The bottom line: If you want the stronger value proposition, the 2020 is the better starting point because it combines a lower average price with solid deal availability. If you are willing to pay more for the next year’s different balance of performance and everyday compromises, the 2021 is the secondary path to consider.
