How much does the 2018 BMW 5 Series cost?

Prices have softened 11.27% compared to this time last year, making it a favorable time to shop this model year.

There are 1,381 listings available, which suggests solid inventory for comparison shopping.

Is the 2018 BMW 5 Series a good car?

Yes — with a 4.95/5 user rating and an 8.33/10 expert rating, this 5 Series lands strongly with shoppers who want a luxury midsize sedan. 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 more practical, efficiency-minded angle thanks to the 530e plug-in hybrid, while still keeping the car firmly in the luxury segment.

That combination makes it a good fit if you want comfort and premium features without giving up everyday usability. Good and great deals account for 35.7% of listings, so there are still worthwhile opportunities in the market.

Is the 2018 BMW 5 Series reliable?

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

The user feedback also points to a dependable-feeling ownership experience, with praise for comfort and handling alongside the smooth ride and luxurious features. 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 in a familiar, easy-to-live-with way.

There are still some caution flags in owner feedback around engine noise and potential reliability issues, so a careful pre-purchase 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 62% 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, repairs, and wear items. Because this model can be optioned heavily, it also pays to confirm that the features you care about are actually present and functioning as advertised.

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. Base versions can be stripped of some advanced equipment, so check carefully for the features you want.
• Powertrain: The plug-in hybrid setup pairs a twin-scroll turbo 2.0-liter engine with an electric motor and a traditional automatic transmission. It delivers strong torque, quick acceleration, and better fuel economy than the gasoline version.
• 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 these items are optional rather than standard, so verify the exact equipment on the car you’re considering.
• Infotainment: The iDrive system includes eDrive pages, and Apple CarPlay is available. Wireless smartphone integration and over-the-air capability are not stated here.
• Fuel efficiency: The 530e is rated at 72 MPGe with a topped-off battery and 29 mpg combined when running on gasoline alone. It can also travel about 16 miles on electric power.

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 path into this model year and value efficiency as much as luxury. It adds the plug-in hybrid setup, strong torque, and the ability to drive on electric power for short trips, while still feeling like a regular BMW sedan in daily use.

The safety-package note to keep in mind is that several desirable driver-assistance features are optional, so you should verify the exact equipment before you buy.

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

This looks like a moderate, selective buyer’s market, so you can shop patiently but should move quickly on the right car.

• Deal availability: 35.7% of listings are priced as good or great deals.
• Inventory: There are 1,381 listings available.
• Price trend: Prices have softened 11.27% compared with last year.
• Clean inventory: 62.0% of listings are accident-free.

If you find a listing below $18,347, 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 $18,347 sits slightly below last year's $20,679.

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. If prices stay soft, future sellers may need to compete more aggressively on condition, mileage, and equipment to stand out.

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?

The 2018 BMW 5 Series 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 available driver-assistance equipment includes blind-spot monitoring, adaptive cruise control, lane-keeping assist, and related autonomous safety and parking features. Some of those features are tied to optional packages rather than standard equipment, so you should confirm what’s installed on any used example.

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:

• 35.7% of listings are priced as good or great deals.
• At 62% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 11.27% compared with last year.
• Owners rate it 4.95/5 — a strong satisfaction signal.
• It adds the 530e plug-in hybrid, making the lineup more efficient and the model year especially appealing for frugal luxury shoppers.

Consider the 2017 if:

• At $17,098, the 2017 costs less than the current year's $18,347 average.
• It brings a full redesign with a fresh chassis, new engines, and updated technology.

The bottom line: If you want the best mix of value, efficiency, and strong owner satisfaction, the 2018 is the better target. If your priority is spending less upfront, the 2017 is the more budget-friendly alternative and still delivers the benefits of the redesign.
