Should one purchase a 2015 650i M Sport?

[CleverPixel]

Hello, I am seeking to replace my 2007 650i with 60,000 miles. I have encountered a 2015 650i M Sport convertible with 28,000 miles online. Nonetheless, the MOT inspection history contains the following:
1. October 2020: FAIL: Offside rear coil spring damaged or broken (5.3.1 (b) (i))

October 2, 2025: FAILURE - Nearside Rear Coil Spring Fractured or Broken (5.3.1 (b) (i)) AND
Observe and rectify if required (recommendations): Oil leak, but not excessive Subsection 8.4.1 (a) (i) pertaining to the lower engine compartment
The offside front lower suspension arm ball joint exhibits minor play (5.3.4 (a) (i)).

The vehicle is located at a Citroen dealership. Do the coil springs on these F series vehicles fracture easily due to misuse? Additional concerns include the oil leak and the arm ball joint.
Should I contemplate or disengage?

Thank you

The rear components of my 2017 F82 M4 have failed at 36,000 miles. I replaced all four for reassurance, opting for Eibach Sport Pro, which was far more economical than BMW parts.

I am astonished that damaged coils occur in vehicles with such low mileage; they typically manifest in older cars, those subjected to potholes, vehicles used on racetracks, or in extremely cold climates.

I do not intend to intrude; please direct me as necessary, but what is the price of the car and what is your budget? If it is £3,000 below market value and requires an investment of £1,500, it is likely a favourable offer. If it is priced at market value and requires an expenditure of £1,500, then it constitutes a poor investment.

The listed price is £19,990.
To repair leaks, the cost ranges from £1,500 to £2,500. If the typical suspects are from an independent garage, is the cost up to £5,000? by BMW thief, but significantly more if it pertains to the head gasket.
Concerns arise from two fractured rear coil springs, which may indicate exposure to harsh terrain or aggressive driving.

Typically, broken springs would not alarm me; nevertheless, their discovery solely during the MOT stage raises questions about the vehicle's maintenance and care. £20,000 for a 2015 model 650? It may be prudent to purchase the M6 and conserve some funds. 😂

Jokes aside, the individual from whom I procure my pre-owned performance automobiles typically possesses some remarkable options in inventory, and I can personally attest from firsthand experience to his rectification of difficulties that develop post-sale. Currently in possession of a pair of substantial specification 7 and 8 series vehicles that appear to be impressive automobiles.


He is undoubtedly deserving of a call, since Josh excels in procuring a diverse array of vehicles, ranging from standard automobiles to Rolls-Royce Cullinans, for his clientele, and his operation is exceptional.

Locate a 2015 M6 with comparable mileage at a reduced price to economise.

I am not an automobile salesperson, therefore I will not be searching for a vehicle on your behalf. 😂

I would prefer to purchase a vehicle with 200,000 miles that has been well-maintained rather than a low-mileage vehicle that is leaking oil, has broken springs, and has suffered a failure of the OEM ball joint, likely due to the excessive pressure from the damaged springs, indicating that the springs have been compromised for an extended period, as most OEM suspension components typically endure 100,000 miles with proper care.


Your initial post unwittingly provided the answer to your query; if you must enquire about the worthiness of a risk on a public forum, you are merely seeking validation that the risk is unwarranted. It is likely the reason it is at a Citroën dealership, following the previous owner's realisation of the costs associated with repairs at a BMW dealer, ultimately leading them to opt for a more economical, French vehicle that would be less expensive to maintain in the future.

I have never seen mine; they snap at the tips. This is only apparent while navigating corners aggressively. My car is not driven recklessly, since I adhere to speed restrictions approximately 90% of the time.However, they failed; I have owned an E90 330d and an E92 335, and the rear components fractured when stationary in the driveway, as did the front components on the E90.I attribute the issue to speed humps; residents in areas with harsh conditions experience this problem. In my locality, some speed humps necessitate driving at 1 mph, which is detrimental to any suspension system. I consulted a garage owner with 40 years of experience, and he indicated that since the implementation of speed humps, the frequency of suspension component replacements has consistently increased.

The N63 engine, a critical component of the 2015 650i, has demonstrated significant reliability issues. The 640i is a significantly superior option.

That is a reasonable assertion; but, I wish to upgrade to a more rapid vehicle with a V8 engine.

I have owned my 2007 650 for almost 14 years. It was inexpensive at the time of purchase and currently has just 60,000 miles. It requires £1,000 to £2,000 to repair engine and gearbox leaks. I may chose to undertake the repairs and retain the vehicle for an additional three years.
