Vehicle Details
AI Listing Summary
This 1986 BMW M635 CSi, one of 524 UK models, features a Diamond Black exterior and Perl Beige interior. It boasts a rebuilt engine and gearbox, but the interior requires attention, impacting its potential value, estimated between £30,000 and £35,000.

Condition
6
The car has had bodywork restoration and engine/gearbox rebuilds, indicating care. However, the interior isn't up to the same standard, with stained seats, aftermarket modifications, and wear/damage to trim. The exterior has minor issues like rust bubbles and paint imperfections, and the wheels have some tarnishing and tire wear. These factors suggest 'Good' condition, requiring some reconditioning.

Finished in the classic colour combination of Diamond Black and Pearl Beige, ‘C6 PBT’ is one of just 524 BMW M635CSi cars built for the UK market.
We understand that its bodywork was professionally restored in 2021 – purportedly costing more than £20,000.
The engine was rebuilt in 2018, followed by the gearbox four years later.
The seller hasn’t been in a position to use it much, hence this sale, but he did drive it to Cornwall without encountering any problems – and he drove it here.
Black and chrome is an iconic colour scheme for a reason.
Full of menace and yet wonderfully upmarket, few cars of the era have the presence as a well-presented M635CSi.
Of course, being a black car, every single dinks, flaw and dent will be highlighted, which makes assessing it an easy matter.
A quick one too, in this case, because there isn’t much to report other than very good shutlines, great alignment, a lovely stance, and an almost complete absence of damage.
The paintwork has a great shine ...
