Is the 2018 BMW M5 a good car?

Yes — owners rate it 5/5, which points to very strong satisfaction with the ownership experience. Reviewers consistently praise the car’s outstanding performance, luxurious interior, and advanced technology, and they also highlight how it can feel comfortable in everyday driving while still delivering serious speed and agility.

With 33.7% 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 review summary also points to a car that owners describe as dependable in the sense that it delivers the performance and luxury they expect without losing its everyday usability. The strongest reliability takeaway for used buyers is that this is a high-performance sedan, so long-term ownership risk rises if the car has been neglected or modified.

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

At 67.3% 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 separate clean examples from cars with accident records. After that, prioritize a thorough pre-purchase inspection, especially on maintenance history, signs of hard use, and overall condition. Because this is a performance-focused sedan, you should pay close attention to whether the car has been modified, neglected, or driven in a way that could affect long-term ownership costs.

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 carefully and still find worthwhile options.

• Deal availability: 33.7% of listings are priced as good or great deals.
• Inventory: There are 101 listings available.
• Price trend: Prices have softened 3.38% compared with last year.
• Clean inventory: 67.3% 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 $48,832.

That price movement suggests the market has softened, which can help you buy more confidently now but may also mean slower appreciation if you plan to resell later. For a future seller, the key is to buy a well-kept example and avoid overpaying, because a cleaner purchase price gives you more room to preserve value. 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:

• 33.7% of listings are priced as good or great deals.
• At 67.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 3.38% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

The bottom line:

If you want the first xDrive-equipped M5 with strong owner satisfaction and a market that has softened a bit, the 2018 is the primary year to target. If you are especially price-sensitive, you can also compare nearby years to see whether a cleaner or better-priced example offers a better overall value, but the 2018 remains the most compelling choice when you want this generation’s blend of speed, traction, and everyday usability.
