How much does the 2018 BMW M5 cost?

Prices have softened 3.44% compared to this time last year, making it a favorable time to shop this model year.

There are 101 listings available, which gives you a modest amount of inventory to compare before you buy.

Is the 2018 BMW M5 a good car?

Yes — the 2018 BMW M5 earns a 5/5 user rating, which points to strong owner satisfaction. Owners consistently praise its outstanding performance, luxurious interior, and advanced technology, and many say it feels comfortable in daily driving while still delivering serious speed and agility. That makes it especially appealing if you want a high-performance luxury sedan that still works as an everyday car. With 30.7% of listings marked as good or great deals, you have some room to shop selectively.

Is the 2018 BMW M5 reliable?

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

The owner feedback also points to a car that feels dependable in the ways that matter to enthusiasts, with repeated praise for its strong performance, comfort, and technology over time. That said, this is a high-performance sedan, so long-term ownership risk for used buyers still depends heavily on maintenance history and how carefully the car was driven and cared for.

What should I look for when buying a used 2018 BMW M5?

At 66.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report so you can confirm accident records, title status, and ownership history before you get too far into the process. After that, prioritize a pre-purchase inspection, especially on a performance car where prior neglect or modifications can matter more than mileage alone. Focus on overall condition, signs of hard use, and whether the car has been maintained consistently.

Is now a good time to buy a used 2018 BMW M5?

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

• Deal availability: 30.7% of listings are priced as good or great deals.
• Inventory: There are 101 listings available.
• Price trend: Prices have softened 3.44% compared with last year.
• Clean inventory: 66.3% of listings are accident-free.

If you find a listing below $47,184, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 BMW M5's resale value?

The current average of $47,184 sits slightly below last year's $48,864.

That price movement suggests the market has eased a bit, which can help you buy more carefully now but may also limit short-term upside if you plan to resell soon. For a future seller, the key is to protect value through strong maintenance records and clean condition, since buyers in this segment tend to reward well-kept examples. A car that presents well and has a clear history should be easier to move when it is time to sell.

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 2018 BMW M5 or consider a different year?

If you're weighing the 2018 against nearby model years, here's how to think about it:

Choose the 2018 if:

• 30.7% of listings are priced as good or great deals.
• At 66.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 3.44% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

The bottom line:

If you want the first xDrive M5 with the blend of all-weather traction, supercar-level speed, and everyday usability, the 2018 is the right direction to focus on. If you are more price-sensitive, you can also compare nearby years to see whether a cleaner or better-priced example gives you a better overall value, but the 2018 remains a compelling choice when condition and history check out.
