BMW 5 Series Depreciation: Best Year to Buy Used for Value

Why the BMW 5 Series Depreciates the Way It Does

Let me be blunt with you. The BMW 5 Series is a brilliant car -- genuinely one of the best executive saloons you can buy in the UK. But that brilliance comes at a cost, and I am not talking about the list price. I am talking about the absolute hammering it takes on depreciation in the first few years of ownership.

A brand-new 5 Series in 520d SE trim will set you back roughly £45,000 to £48,000 on the road. Drive it home and you have already lost somewhere between £4,000 and £6,000 in value. By the end of year one, that figure climbs to around £10,000 to £12,000. That is roughly 22-25% gone in twelve months. Painful, right?

The reason is straightforward. BMW produces a lot of 5 Series models, and a huge proportion end up on fleet and company car schemes. When those PCP and lease deals expire after three years, the used market gets flooded with well-specced, low-mileage examples. Supply goes up, prices come down. It is basic economics, and it works massively in favour of the second or third owner.

The 5 Series Depreciation Curve -- Year by Year

Here is how a typical BMW 520d SE depreciates over time, based on what I see in the UK market:

• Year 1: Down roughly 22-25%. A £47,000 car drops to around £36,000.
• Year 2: Down roughly 35-38% from new. Now worth about £30,000.
• Year 3: Down roughly 45-50% from new. Worth approximately £24,000 to £26,000.
• Year 4: Down roughly 52-57%. Worth around £20,000 to £22,000.
• Year 5: Down roughly 58-63%. Worth approximately £17,500 to £19,500.
• Year 6-7: Down roughly 65-72%. Worth around £13,000 to £16,000.
• Year 8-10: Down roughly 75-82%. Worth approximately £8,500 to £12,000.

Notice something? The steepest drops happen in years one through three. After year four or five, the curve flattens out considerably. That flattening is where the opportunity lies for savvy buyers.

The Sweet Spot -- Best Age to Buy a Used BMW 5 Series

If you ask me the single best age to buy a 5 Series, I will tell you three to four years old every single time. Here is why.

At three years old, the car has already shed roughly half its original value. You are picking up a £47,000 saloon for £24,000 to £26,000. It will still have relatively low mileage -- typically 30,000 to 45,000 miles if it was a company car. There is a good chance it still has some manufacturer warranty remaining or can be covered by an approved used warranty.

The depreciation from year three to year five is only about £5,000 to £7,000 in total. Compare that to the £21,000 to £23,000 it lost in its first three years. You are losing far less per year of ownership, which means your actual cost of driving a BMW 5 Series plummets.

If budget is tighter, the five to six year mark is another solid window. The car will be worth around £15,000 to £18,000, and your annual depreciation drops to roughly £1,500 to £2,500. You will need to budget more for maintenance at this point, but the overall running costs can still work out cheaper than buying new.

What About Older 5 Series Models?

Once you get beyond eight years, you are looking at a car that has bottomed out in value terms. An F10 generation 5 Series (2010-2017) at ten years old can be picked up for £6,000 to £10,000 depending on spec and mileage. These barely depreciate any further -- you might lose £1,000 a year at most. The risk shifts from depreciation to maintenance costs, so factor in a healthy repair budget.

Which 5 Series Variants Hold Their Value Best?

Not all 5 Series models depreciate at the same rate. Some hold their ground significantly better than others.

Diesel models -- particularly the 520d -- are the most common on the used market and depreciate the most in absolute terms simply because there are so many of them. However, they also tend to be the cheapest entry point, so they can represent excellent value.

The 530e plug-in hybrid has been holding up better in recent years. Company car tax advantages mean strong demand from private buyers looking for a pre-registered or nearly-new bargain, but the low BIK rates also mean fewer come to market as early, which props up values.

The M550i and M5 hold their value far better in percentage terms. An M5 Competition that listed at £105,000 might still fetch £65,000 to £70,000 after three years. That is only about 33-35% depreciation compared to the 50% for a standard 520d. Performance BMW models have a dedicated following, and supply is much more limited.

M Sport trim consistently outperforms SE trim on resale. The visual upgrades, larger wheels, sports suspension, and interior enhancements are what most buyers want. If you are choosing between an SE and an M Sport at similar money, always go M Sport -- you will get more back when you sell.

Specification and Colour Matter

Black, white, grey, and blue 5 Series models sell fastest and hold value best. Unusual colours can sit on forecourts longer, which pushes prices down.

Before buying, you can check the exact road tax cost on GOV.UK using the registration number.

Individual options like the Technology Pack, Comfort Pack, and head-up display are desirable and add to resale value. Conversely, a bare-spec 520d SE in beige with cloth seats will struggle more than most.

Factors That Affect BMW 5 Series Resale Value

Beyond age and mileage, several factors will influence what your 5 Series is worth when you come to sell.

Service history is absolutely critical. BMW buyers expect full BMW dealer or BMW specialist service records. A car with gaps in its service history can lose 10-15% compared to an identical car with a complete book.

Mileage matters, but perhaps less than you think once you get beyond 60,000 miles. The difference between a 60,000-mile and an 80,000-mile 5 Series might only be £1,000 to £2,000. However, sub-30,000 mile examples command a noticeable premium.

MOT history is something buyers check religiously these days. A string of advisories for suspension wear, brake disc condition, or tyre issues signals a car that has had a hard life. Clean MOT records support stronger values.

Outstanding finance is another hidden value killer. A significant number of used 5 Series cars still have finance owing on them. If you buy one without checking, you could lose the entire car to the finance company. Always verify this before handing over any money.

How to Minimise Depreciation When Buying

Here are my top practical tips for keeping your 5 Series depreciation losses to a minimum:

1. Buy at three to four years old rather than new. Let someone else absorb the biggest hit.
2. Choose M Sport trim -- it costs slightly more upfront but returns significantly more at resale.
3. Stick to popular colours -- black, grey, white, and blue metallic are the safe bets.
4. Look for well-specced cars with Technology Pack, leather, and navigation as a minimum.
5. Keep mileage reasonable -- try to stay under 10,000 to 12,000 miles per year.
6. Maintain the full service history with a BMW dealer or recognised specialist. Never skip a service to save a few quid.
7. Keep the car in good cosmetic condition -- alloy wheel scuffs and interior wear knock hundreds off the resale price.

Dave's Verdict -- When to Buy and What to Watch For

The BMW 5 Series is one of the best used car bargains in the UK executive segment, but only if you time your purchase correctly. Buying new is essentially setting fire to money -- you will lose £20,000 or more in three years.

My recommendation? Target a three to four year old 520d or 530e in M Sport trim with a full service history and between 25,000 and 40,000 miles. You will pay roughly £23,000 to £28,000 for a car that cost nearly twice that new, and your ongoing depreciation will be manageable.

Before you commit to any specific 5 Series, though, you absolutely need to know what you are getting into. Hidden finance, outstanding recalls, dodgy mileage, accident damage that has been conveniently forgotten -- these are all things that can turn a bargain into a money pit overnight.
