How much does the 2018 BMW 5 Series cost?

Prices have softened 11.60% compared to this time last year, making it a favorable time to shop this model year.

There are 1,455 listings available, which suggests solid inventory for comparison shopping. If you find a listing below $18,519.99, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2018 BMW 5 Series a good car?

Yes — the 2018 BMW 5 Series earns a 4.95/5 user rating and an 8.33/10 expert rating. The standout strength is Cost effectiveness at 10/10.

Owners consistently praise the smooth ride, powerful performance, and luxurious features. The overview also points to a refined midsize luxury sport sedan with strong performance, while the plug-in 530e adds frugality to the mix. That combination makes the car especially appealing if you want comfort and efficiency more than a purely sporty character.

With 35.0% of listings marked as good or great deals, the market still gives you room to shop selectively.

Is the 2018 BMW 5 Series reliable?

Owners rate it 4.95/5, a strong signal of long-term satisfaction.

The owner summary also points to a car that many drivers find satisfying over time, with comfort and handling standing out alongside the smooth ride and strong performance. At the same time, some owners mention potential reliability issues, so you should treat maintenance history as a priority when shopping used.

The performance notes reinforce that the 530e uses a traditional automatic and delivers its power in a way that feels familiar, which can help long-term ownership feel less complicated than some hybrids. The cost-effectiveness discussion also emphasizes that it can be a lower-cost way into a 5 Series, which may help offset ownership concerns if you buy carefully.

For used buyers, the main risk is that a neglected example could turn the ownership experience from upscale to expensive quickly.

What should I look for when buying a used 2018 BMW 5 Series?

At 62.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a pre-purchase inspection, especially on cars with higher mileage or visible cosmetic wear. Focus on signs of prior bodywork, uneven panel gaps, tire wear, brake condition, and any warning lights or electrical quirks. Because this model can be option-heavy, make sure the features you care about actually work as intended.

Key things to evaluate:

• Trim level: The 530e differs only slightly from the gasoline-powered 5 Series, but it does have eDrive badging, a charging port, ambient lighting, a flush LED gauge cluster, and a reduced trunk. It also may lack some features unless the car was optioned up, including advanced safety and parking equipment.
• Powertrain: The plug-in hybrid setup delivers strong acceleration, with the 530e reaching 60 mph in about 6 seconds and returning 72 MPGe when charged. When the battery is depleted, it still returns 29 mpg combined.
• Safety package: The car can be equipped with driver-assistance packages, and the safety content notes a strong crash-test result. Some useful features may be optional rather than standard, so verify what the specific car includes.
• Infotainment: The iDrive system includes eDrive pages, and the car can be optioned with Apple CarPlay, wireless charging, Wi-Fi hotspot capability, and enhanced connectivity. Gesture Control is mentioned, but it is described as unreliable.
• Fuel efficiency: The plug-in hybrid setup is rated at 72 MPGe with a charged battery and 29 mpg combined once the battery is depleted.

Which 2018 BMW 5 Series trim should I buy?

The 2018 BMW 5 Series is offered in 1 trim level: 530e.

Here's the short version:

The 530e is the clear pick because it combines the lowest entry price in the lineup with strong efficiency and quick acceleration. It also gives you the plug-in hybrid experience without giving up the familiar feel of a traditional automatic.

Close attention should go to the option sheet, because many desirable features were extra-cost items. If you want the best value, look for a well-equipped example with the driver-assistance and convenience features you actually plan to use.

What is the 2018 BMW 5 Series's resale value?

The current average of $18,515 sits slightly below last year's $20,945.

That price movement suggests the market has already adjusted downward, which can help you buy at a more favorable entry point today. For a future seller, that also means resale value may depend more heavily on condition, mileage, and equipment than on broad market momentum.

Because this model year has strong owner satisfaction, well-kept examples should continue to attract interest. Vehicles with strong owner satisfaction ratings, like this model year's 4.95/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2018 BMW 5 Series 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:

• 35.0% of listings are priced as good or great deals.
• At 62.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 11.60% compared with last year.
• Owners rate it 4.95/5 — a strong satisfaction signal.
• The 530e plug-in hybrid adds frugality to the lineup and is the lowest-priced 5 Series you can get.

Consider the 2017 if:

• At $16,955, the 2017 costs less than the current year's $18,515 average.
• It is a thoroughly renewed redesign with a fresh chassis, new engines, and updated technology.

The bottom line: If you want the better-balanced buy, the 2018 is the stronger choice because it combines a lower average price than last year with strong owner satisfaction and the added appeal of the 530e. If your top priority is spending less up front, the 2017 is worth a look, especially if you value the freshness of its redesign and can find a clean example.
