Full History

     he 850 CSI is still considered by many as the last true Bahn storming, low volume, BMW M built GT Car. Only 160 of these very special and highly expensive cars were built over a 3-year period in right hand drive. It is as close as we got to the M8 with BMW having canned the M8 after the production of just one prototype. It was a change of direction for BMW M that led to the decision that the M badge no longer lived on a big GT car. The 850 CSI was largely BMW M inspired with a massive input from their engineers in suspension, steering, brakes, engine and aerodynamics. Whether the 850 CSI is the best high-speed cross  continent crushing GT to ever leave BMW M, continues to be debated even now, 32 years later . A very clever blend of high performance and handling with luxury still rarely seen today. M inspired and very low volume has to make this a true must for the most serious of car collectors. 


All 850 CSI were 6 speed manual and fitted with limited slip differential as standard. BMW M made numerous upgrades to the M70 engine which was increased to 5.6 litres. These mods with improved inlet and exhaust took the power to an impressive 380 bhp and 550 Nm of torque. Front springs, rear springs and shocks were uprated by M and BMW’s four-wheel steer system became standard on the CSI. The front brakes were larger than the standard 850 and had been upgraded to Brembo calipers. The interior on the standard car was already an extraordinarily high specification but the CSI saw red needles added to the instruments along with a striped M Badge gear knob, door sill plates and engine cover. Externally the CSI benefited from revised M front and rear spoilers, sill skirts, aerodynamic mirrors, and a fantastic looking exhaust system.

This particular example, presented in individual Barbados Green is very well known to Hero Motor Company. Paired with Anthrazit Buffalo leather and very hard to find genuine 18” Alpina alloy wheels, this beautiful 850 CSI boasts an amazing document file which gives you an insight into the fastidious level of care that has been lavished on this car by the previous owners. 


Having covered only 59,000 miles and featuring an impeccable and documented service history, this car has been in the care of the current owner not once, but twice. It was simply too good to let go the first time.

David, was on the lookout for a powerful, comfortable, modern performance GT with classic styling. Having considered the Porsche 928 and Mercedes 500SL, in 2000 he came across this Barbados Green 850 CSI. Having not been on his radar, it was love at first sight. Following a road test at his local BMW dealership, the deal was done and this 850 CSI found a new home in Davids purpose built, heated and dehumidified garage.


In 2007 David was forced to put the 850 CSI up for sale.

The loss for David was simply too great. The car had played such a major part in David's 7 year ownership having been the chosen carriage for the first date with his now wife.  Suffering this emotional loss David set about finding his beloved 850 CSI with the hope of persuading the new owner to sell it back to him. A flurry of phone calls would result in this one of a kind 850 CSI being reunited with a very grateful David.
