BMW 6 Series 630i, timeless elegance in as-new condition
The history of BMW is steeped in innovation, driving pleasure and German precision. Since its founding in 1916, the marque has grown into a global icon in the world of sporting luxury cars. The 6 Series holds a special place within that story: a gran turismo that blends performance and comfort seamlessly.
The second generation of the 6 Series, known internally as the E63 (coupé) and E64 (convertible), was introduced in 2003 and marked a bold design direction led by designer Chris Bangle. With its flowing lines, long bonnet and powerful presence, the 6 Series broke with traditional shapes and set a new benchmark in the luxury coupé segment.
The BMW 630i is a particularly well-balanced version within this range. Beneath the bonnet sits a refined straight-six petrol engine renowned for its suppleness, reliability and characteristic smoothness. This engine embodies exactly what made BMW great: driving pleasure without compromise.
A BMW 630i in exceptional condition
This particular BMW 6 Series 630i from October 2006 is in a state you rarely come across. With only 65,929 kilometres on the clock and a first owner from new, this car radiates originality and care in every detail.
What makes this car truly unique is its provenance and service history. It has always been maintained by the very same BMW dealer that supplied it new. That means full transparency, craftsmanship and an unbroken service record, exactly as it should be for an enthusiast's car.
The paintwork, in the elegant shade Barbera Red Metallic, is entirely original first paint and is in exceptionally beautiful condition. The exterior gleams just as the factory intended, without compromise. The interior, finished in black leather, matches it seamlessly: crisp, fresh and with barely a trace of use, a rare level of care that fully justifies the term "as-new".
The automatic transmission shifts smoothly and contributes to the comfortable yet dynamic driving character for which the BMW 630i is known. Everything about this car breathes quality, precision and passion.
Experience and invitation
A car like this should not merely be seen, but experienced. Opening the heavy coupé door, settling into the leather interior and firing up the silky-smooth straight-six: it is a complete experience that takes you back to the very essence of driving.
We warmly invite you to come and admire this special BMW 630i for yourself in our showroom in Katwijk. The coffee is ready, and we are happy to take all the time you need to experience this exceptional car up close.

What should you look for when buying a BMW 6-Serie (E63)?
Engine & drivetrain
The main points of attention lie in the engines. Know which one you are buying.
- V8 (645Ci/650i, N62) — valve stem seals. This is the well-known affliction. Versleten klepsteelkeerringen veroorzaken olieverbruik en blauwe rook, vooral na langer stationair draaien en bij koude start. De reparatie is arbeidsintensief. In de VS rekenen dealers richting $ 7.000–$ 9.000; onafhankelijke specialisten met de juiste gereedschappen vaak rond $ 2.500–$ 5.000. In het VK lagen offertes doorgaans rond £ 1.300–£ 2.500, bij demontage van de koppen hoger. Reken op een forse rekening; laat bij elke V8 kort stationair draaien en let op rook.
- Cooling system (all petrol engines). Many plastic components age: electric water pump, thermostat housing, coolant lines and radiator end tanks. A failing water pump can cause sudden overheating. Replace proactively; neglected overheating can lead to warped cylinder heads.
- Oil leakage. The valve cover gaskets and the oil filter housing tend to leak over the years. Oil on hot components and on belts is a point of concern.
- M6 (S85 V10). Notorious for wear of the rod bearings, particularly without meticulous maintenance; preventive replacement is recommended. The SMG pump and the VANOS solenoid valves can also fail. Insist on a complete, dated service history.
- 635d (M57). Watch for a failing thermostat, DPF clogging and the well-known swirl flap issues in the intake manifold.
Bodywork & rust
- The bodywork panels are zinc-coated steel with aluminium doors and bonnet. Rust is generally not a major concern.
- Do note aluminium corrosion at the upper trim strip of the doors.
- On the E64 convertible: check the operation of the roof mechanism and inspect for leaks; parts for the roof locking are available.
Interior & electrical
- The electronics are complex. Frequently reported complaints: windows, central locking, navigation/iDrive and dashboard lighting.
- Battery drain (parasitic drain) does occur; check whether the car starts readily after standing idle.
- Scan for fault codes relating to the Valvetronic and VANOS components.
History & documentation
- On the V8 and M6, a complete, dated service history is not a luxury but a prerequisite. Missing major service items are a red flag.
- Search the history for documented work on the valve cover/valve stem seals and cooling system; for the M6, on the connecting rod bearings.
- A cold start, test drive and diagnostic read-out before purchase prevent the most costly surprises.
Which BMW 6-Serie (E63) suits you?
If you mainly drive and seeking low running costs, is best served most carefree by the 630i: the inline-six is the safest and the only one readily found with a manual gearbox. Those seeking the V8 character and sound choose the 645Ci or 650i — but buy it with care, keeping an eye on the valve stem seals and history.
De M6 with V10 is available for those collector or the driver prepared to invest in meticulous maintenance; it is a car to cherish, not to neglect. Between coupé (E63) and convertible (E64) it is mainly a matter of taste and use; the coupé is structurally simpler.

What does a BMW 6-Serie (E63) cost?
The Dutch and European pricing picture in 2026 is broad, because engine, condition and history vary widely. Based on current listings (autumn 2026) we observe the following. Note: do not confuse the E63/E64 with the much newer '6 Series Gran Turismo 630i' (from 2017), which is more expensive and concerns a different model.
De 630i coupé and convertible form a large part of the market. Tidy examples are typically offered in the Netherlands between around €5,500 and €20,000, depending on mileage, history and condition. High mileage and poorer history push the price towards the lower end of that range.
De V8 models (645Ci/650i) are roughly between around €10,000 and €28,000, with a median of around €20,000 for well-maintained cars; early, neglected V8s sometimes change hands for less. The M6 with V10 sits above that and has a wider range, with pristine, well-documented examples being the most sought-after.
Price is determined above all by: engine choice, documented history, mileage, condition of the cooling system and (on the V8) whether the valve stem seals have already been addressed. A car with proven maintenance is worth its premium.
