BMW 5 Series: Best Years and Years to Avoid
The 5 Series spans everything from cheap high-mileage diesels to complex V8s, so generation alone tells you little. The G30 is the safe modern choice, the F10 is strong on the right engine, and the E60 rewards careful buyers while punishing careless ones. Risk here is engine-specific, not generation-wide.
Quick answer
Best all-round pick: a G30 520d or 530i, or an F10 520d/530d with history. Be most careful with the V8 550i (N63) and any early N47 diesel. The six-cylinder diesels are the durable heart of the range; the V8s reward only well-documented, deep-pocketed buyers.
G30 / G31 (2017-present) Buy
Chassis: G30, G31
The current 5 Series is a refined, well-sorted used car built around BMW's reliable B-series engines. The mainstream 520d and 530i are the sensible choices; only the V8 M550i/550i carries the usual big-engine caveats.
| Best years | Any G30 520d, 530d or 530i is a solid buy. Later cars benefit from the 2020 facelift's updated infotainment. |
| Years to watch | M550i and 550i models use the N63 V8; treat those like the F10/E60 V8s and demand full history. |
| Engines to trust | 520i (B48), 530i (B48), 520d (B47), 530d (B57), 540i (B58) |
| Engines to check | M550i / 550i (N63 V8), 530e plug-in hybrid (battery checks) |
Key risks
- N63 V8 (550i/M550i): coolant transfer pipe, timing chain guides and high oil consumption
- B57/B47 diesels need regular DPF regeneration; avoid short-trip-only cars
- Occasional early-car software and infotainment glitches
F10 / F11 / F07 (2010-2017) Mixed
Chassis: F10, F11, F07
A durable executive saloon on the right engine, and a money pit on the wrong one. The six-cylinder diesels are the backbone of the range and age well; the four-cylinder N47 and the V8 550i are the ones that need careful vetting.
| Best years | 2013-2017 530d (N57/B57) or 520d (B47, later cars) with full history are the durable, efficient sweet spot. The 535i (N55) is a smooth, relatively robust petrol six. |
| Years to watch | Early N47 520d cars (2010-2012) for the rear timing chain, and any 550i or M5 for V8 running costs. |
| Engines to trust | 530d (N57), 535d (N57), 535i (N55), 520d (B47, later) |
| Engines to check | 520d (N47 timing chain, early cars), 550i (N63 V8), M5 (S63 V8) |
Key risks
- N47 diesel rear timing chain on early 520d cars
- N63 V8 (550i): coolant transfer pipe, injectors, timing chain guides and turbo oil use
- Diesel swirl flaps, EGR and DPF issues on neglected or short-trip cars
- S63 M5: high running costs and rod-bearing scrutiny on hard-used examples
E60 / E61 (2003-2010) Caution
Chassis: E60, E61
Now cheap to buy but potentially expensive to keep, the E60 is a connoisseur's used car. The straight-six diesels and the N52 petrol can be dependable; the early V8s and the S85 V10 M5 carry serious, well-documented cost risk. Buy on evidence, not optimism.
| Best years | 2007-2010 LCI 525d/530d (M57/N57) or 523i/525i (N52) with a strong service file are the safest way into an E60. |
| Years to watch | The 545i/550i (N62 V8) for valve stem seals and coolant transfer pipe, the 535i (N54) for fuel-pump issues, and the M5 (S85 V10) for rod bearings and VANOS. |
| Engines to trust | 523i / 525i (N52), 525d / 530d (M57/N57) |
| Engines to check | 545i / 550i (N62 valve stem seals), 535i (N54 HPFP), M5 (S85 V10 rod bearings) |
Key risks
- N62 V8: valve stem seals (blue smoke on start-up), coolant transfer pipe and timing chain guides
- S85 V10 (M5): rod bearings, VANOS units, throttle actuators and SMG gearbox costs
- N54 (535i): high-pressure fuel pump and injector failures
- Ageing electronics, cooling systems and rust on high-mileage cars
The pick of the range
The value sweet spot is a 2013-2017 F10 530d (N57) with full service history: a smooth, long-legged straight-six diesel that regularly covers 200,000-plus miles when maintained. If you want the newest platform, a G30 520d or 530i is the safer long-term choice. Petrol buyers who prefer simplicity should look at an E60 or F10 with the naturally aspirated N52 six.
What to avoid, and why
The combinations to approach with most caution are the V8 550i (N63 in F10 and G30, N62 in E60 545i/550i) and the early N47 520d without chain-replacement receipts. The N63 is prone to coolant transfer pipe and timing-chain-guide failures and heavy oil consumption; the N62 to valve stem seals. The E60 M5's S85 V10 is a specialist ownership with rod-bearing and VANOS costs. Buy any of these only with deep documentation and a healthy maintenance fund.

Frequently asked questions
What is the most reliable BMW 5 Series year?
The G30 generation (2017 on) with a 520d, 530d or 530i is the most reliable choice. Among older cars, a 2013-2017 F10 530d (N57) is the durability benchmark, with straight-six diesels regularly exceeding 200,000 miles.
Which BMW 5 Series should I avoid?
No generation is a blanket avoid, but the V8 550i (N63) and early N47 520d cars need the most caution. The N63 has costly coolant and timing-chain-guide issues; the N47 has an expensive rear timing chain. Buy these only with strong evidence of the relevant repairs.
Is the F10 5 Series reliable?
Yes, on the right engine. The six-cylinder diesels (530d/535d, N57) and the N55 petrol are durable. The early four-cylinder N47 diesel and the V8 550i need careful vetting for timing-chain and coolant-system history respectively.
Is the BMW 550i V8 reliable?
The N63 V8 in the 550i is powerful but maintenance-heavy, with documented coolant transfer pipe failures, timing chain guide wear and high oil consumption. It can be owned successfully, but only with full history and a budget for preventative work.
Petrol or diesel 5 Series for the UK?
For the typical high-mileage 5 Series buyer, a six-cylinder diesel (520d/530d) is the natural fit and ages well. If your mileage is lower or mostly urban, a B48 or N52 petrol avoids DPF and EGR complications.
Is the E60 M5 a good buy?
Only for buyers who understand its costs. The S85 V10 is spectacular but needs rod bearings monitored, VANOS units and throttle actuators serviced, and the SMG gearbox maintained. Cheap purchase prices hide potentially large bills.
