How much does the 2018 BMW 5 Series cost?

Prices have softened 9.06% compared to this time last year, making it a favorable time to shop this model year.

There are 1,347 listings available, which gives you a solid amount of inventory to compare.

Is the 2018 BMW 5 Series a good car?

Yes — the 2018 BMW 5 Series earns a 4.9/5 user rating and an 8.3/10 expert rating. The standout strength is Cost effectiveness at 10/10. Owners repeatedly praise the smooth ride, powerful performance, and luxurious features, and the model’s plug-in hybrid setup adds efficiency to the mix. That makes it especially appealing if you want a midsize luxury sport sedan that leans more toward comfort and frugality than outright sport. There are 35.9% good and great deals in the market, which suggests you can still find attractive pricing.

Is the 2018 BMW 5 Series reliable?

Owners rate it 4.9/5, a strong signal of long-term satisfaction. The owner feedback also points to a car that feels smooth, comfortable, and generally satisfying to live with, while still delivering the kind of performance and luxury buyers expect. The expert evaluation emphasizes that the plug-in hybrid version is the lowest-priced 5 Series you can get, which can make ownership feel more rewarding if you value efficiency and upscale features together. Still, some owners mention engine noise and possible reliability concerns, so a careful used-car inspection matters if you want to reduce long-term ownership risk.

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

At 59.5% 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 if the car has been optioned heavily or shows signs of prior bodywork. Focus on overall condition, evidence of consistent maintenance, and whether the hybrid and luxury features operate as expected. If you’re comparing multiple listings, the cleanest example is usually worth paying more for.

Key things to evaluate:

• Trim level: The 530e differs only slightly from the gasoline-powered 5 Series, with eDrive badging, a charging port on the front fender, ambient lighting in BMW blue, and a flush LED gauge cluster. It also gives up some trunk space, so you should check whether that tradeoff works for your needs.
• Powertrain: The plug-in hybrid setup adds electric torque and strong efficiency, with a traditional automatic transmission that still shifts like a regular car. It’s described as quick and planted, with rear-biased weight distribution that helps it feel balanced.
• Safety package: The car can be equipped with driver-assistance packages that add blind-spot monitoring, adaptive cruise, lane-keeping assist, and related features. Some of those features are optional rather than standard, so verify exactly what the car you’re considering includes.
• Infotainment: The iDrive system includes additional eDrive pages, and the car can be equipped with Apple CarPlay, a Harman Kardon sound system, wireless charging, Wi-Fi hotspot capability, and enhanced connectivity. Some of those features were optional, so confirm the equipment list carefully.
• Fuel efficiency: The plug-in hybrid setup is rated at 72 MPGe when the battery is topped off, 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: This is the trim to focus on if you want the lowest-priced 5 Series with the plug-in hybrid drivetrain, strong efficiency, and the same quick acceleration as the conventional version. It’s the best-value choice if you want luxury and frugality together, but you should pay close attention to the options list because many desirable features were still extra-cost items.

The safety package can include driver-assistance features, but some of the most useful items remain optional, so check the build sheet before you buy.

Is now a good time to buy a used 2018 BMW 5 Series?

This looks like a moderate market for selective buyers, with enough inventory and enough deal activity to make comparison shopping worthwhile.

• Deal availability: 35.9% of listings are priced as good or great deals.
• Inventory: There are 1,347 listings available.
• Price trend: Prices have softened 9.06% compared with last year.
• Clean inventory: 59.5% of listings are accident-free.

If you find a listing below $18,130, that's toward the low end of the year-round range and worth acting on quickly.

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

The current average of $18,298 sits slightly below last year's $20,121.

That decline suggests the market has already adjusted downward, which can help you as a buyer today but may limit upside if you plan to resell soon. On the other hand, the lower entry price can make the car easier to move later if you buy well and keep mileage and condition in check. Strong equipment, clean history, and good maintenance records should matter more when you eventually sell.

Vehicles with strong owner satisfaction ratings, like this model year's 4.9/5, tend to retain buyer demand, which supports resale value over time.

Is the 2018 BMW 5 Series safe?

The 2018 BMW 5 Series earns a five-star safety 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 notes that the car can be equipped with driver-assistance packages, and those packages add features such as blind-spot monitoring, adaptive cruise, lane-keeping assist, and related technology. If you’re shopping used, make sure the specific car you’re considering has the safety equipment you want, because some of it was optional. The expert notes also mention a middle-of-the-pack stopping distance with the optional M Sport Brakes, which is worth keeping in mind if you’re comparing heavily optioned examples.

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:

• 35.9% of listings are priced as good or great deals.
• At 59.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 9.06% compared with last year.
• Owners rate it 4.9/5 — a strong satisfaction signal.
• It adds the 530e plug-in hybrid, which makes this year especially appealing if you want efficiency and luxury together.

Consider the 2017 if:

• At $16,976, the 2017 costs less than the current year's $18,298 average.
• It brings a thoroughly renewed chassis, new engines, and updated technology.

The bottom line: If you want the most distinctive version of this generation and value efficiency, the 2018 is the better pick. If your priority is simply spending less up front, the 2017 is the smarter budget alternative.

How does the 2018 BMW 5 Series compare to the 2018 Mercedes-Benz E-Class?

Our experts score the 2018 BMW 5 Series 8.3/10 and the 2018 Mercedes-Benz E-Class 8/10. The BMW is the better value here, with a lower average used price and a stronger expert score. The Mercedes-Benz E-Class is priced higher but still posts a slightly better good-and-great deal share. If you want the more efficient and more affordable option, the BMW has the edge; if you want a traditional luxury sedan alternative, the E-Class remains a credible comparison.
