How much does the 2018 BMW 5 Series cost?

Prices have softened 12.30% compared to this time last year, making it a favorable time to shop this model year.

There are 1,454 listings available, which gives you a solid amount of inventory to compare before you buy.

If you find a listing below $18,381.75, 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 model also fits buyers who want a refined midsize luxury sport sedan with upscale comfort and strong performance, while the plug-in 530e adds a more frugal angle to the lineup.

With 29.1% 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 feedback also points to a car that feels dependable in daily use, with repeated praise for comfort, smooth driving, and the kind of ownership experience people can count on. On the expert side, the 530e is described as planted and solid, and it still shifts like a regular car, which supports the sense that it behaves more like a conventional sedan than a finicky hybrid.

If you buy used, the main long-term ownership risk is that some drivers have noted engine noise and possible reliability concerns, so a careful pre-purchase inspection matters.

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

At 62.8% 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 thorough inspection of bodywork, alignment, and any signs of prior repair. Because this model year can show a wide spread in condition, it’s smart to focus on maintenance records, charging-system health on the 530e, and whether the car’s luxury features still work as intended.

Key things to evaluate:

• Trim level: The 530e differs only slightly from the gasoline-powered 5 Series, with eDrive badging, a charging port, BMW blue ambient lighting, and a flush LED gauge cluster. It also gives up some practicality, including reduced trunk capacity and a smaller fuel tank.
• Powertrain: The 530e plug-in hybrid pairs a turbocharged 2.0-liter engine with electric assist, making it quicker than you might expect and capable of strong efficiency when the battery is charged. It also uses a traditional automatic, so it should feel more familiar than many hybrids.
• Safety package: The available driver-assistance content can include blind-spot monitoring, adaptive cruise, lane-keeping assist, and other autonomous safety and parking features. Some of these features are optional rather than standard, so check the exact equipment on the car you’re considering.
• Infotainment: The cabin uses BMW’s iDrive interface with additional eDrive pages, and Apple CarPlay is available as an option. Wireless charging, Wi-Fi hotspot capability, and enhanced connectivity may also appear with the right package.
• Fuel efficiency: The 530e is rated at 72 MPGe with a topped-off 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 trim to focus on if you want the lowest-priced 5 Series in this lineup, plus the added appeal of plug-in hybrid efficiency. It’s the best-value choice here because it combines strong performance, better fuel economy, and a lower starting price than the conventional 530i. If you want the most complete version, look for examples with the driver-assistance and convenience packages, since the base car leaves some desirable luxury and safety tech on the options list.

The safety package can add blind-spot monitoring, adaptive cruise, lane-keeping assist, and other advanced features, so verify exactly what’s installed before you buy.

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

The current average of $18,375 sits slightly below last year's $20,952.

That drop suggests the market has already absorbed a meaningful amount of depreciation, which can help future resale stability if you buy at the right price. For a seller, that also means your upside is better if you choose a well-kept example with strong equipment and clean history.

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.

Is the 2018 BMW 5 Series safe?

It earns a five-star rating from NHTSA and a Top Safety Pick+ rating from IIHS.

It earns a 9/10 safety score from our experts.

The safety content also points to a strong braking result, with a 124-foot stopping distance when equipped with the optional M Sport Brakes. The available driver-assistance content can include blind-spot monitoring, adaptive cruise, lane-keeping assist, and other autonomous safety and parking features, though some of that equipment is optional rather than standard.

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:

• 29.1% of listings are priced as good or great deals.
• At 62.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 12.30% compared with last year.
• Owners rate it 4.95/5 — a strong satisfaction signal.
• The 530e plug-in hybrid is the lowest-priced 5 Series you can get, adding frugality to the lineup.

Consider the 2017 if:

• At $16,979, the 2017 costs less than the current year's $18,375 average.
• It’s a thoroughly renewed 5 Series with a fresh chassis and new engines.

The bottom line: If you want the better all-around buy, the 2018 is the stronger pick because it adds the plug-in hybrid 530e and still benefits from strong owner satisfaction and a softer price trend. If your priority is spending less up front, the 2017 is the value alternative, especially if you want the redesigned platform without paying the 2018 premium.
