Classic & Sports Car – Buyer’s guide: BMW E9 coupés

Why you’d want a BMW E9 coupé

BMW was on a roll in the 1960s, introducing bigger, more sophisticated models. Its recovery began with the 700, followed by the sporty Neue Klasse saloons. For the NK coupés, the 2000 C/CS of 1965, design chief Wilhelm Hofmeister and Manfred Rennen took their cues from the Giugiaro-penned 3200 CS. The shape was deftly facelifted on a longer wheelbase to become the E9, launched as the 2800 CS in ’68.

At full capacity making mainstream saloons, BMW decided to have the low-volume coupés built by Karmann. The E9 CS was nicely finished and expensive – indeed, the 3.0 CSA cost more in the UK than an Aston Martin DBS or a Jensen Interceptor. Good though build quality and equipment levels were – there was even a drop-down tray full of tools and spares in the panelled bootlid – under the skin the news was not so good. Karmann’s rust protection was minimal.

Values fell to rock bottom in the 1980s when many cars were neglected. Finally the rare, homologation-special CSL began to attract attention. Just 1265 were made, using thinner steel throughout, plus aluminium bonnet, bootlid and doorskins. It is now highly collectable, the ultimate being the 3.2-litre ‘Batmobile’.

Outside the UK, left-hookers had Perspex side windows, polycarbonate bumpers, plus no power steering or soundproofing and less trim – but many were specified with normal glass and even steel doors. Alpina-modified cars are even more sought-after. As CSL prices surged, interest increased in the svelte, highly usable coupé from which it was derived. They all cost much the same to restore: roughly £35,000 for a professional bodywork rebuild, and c£50k for the mechanicals plus trim.

Some CSLs have been reshelled into standard bodies: carefully touch the roof to see how thin it is. Sourcing a rot-free E9 from the US is tempting, although it will need other work; the engines were lower compression, and had power-sapping emissions equipment from late 1972, plus 5mph impact bumpers from late ’73. Most exterior trim is available, but some items can be difficult to fit, so assess what is missing if buying a project. 

Build details are available from BMW Classic; the VIN should be on the heater bulkhead, on a plate in the engine bay, on the ring around the starter and on the transmission case. CSLs begin 2-275- (2-285- RHD), bar the first 169 (2986cc engine), which were in the 3.0 CS range (2-210- to 2-212-). See e9-driven.com/E9_Vins.asp for more information.

BMW E9: what to look for

Classic & Sports Car – Buyer’s guide: BMW E9 coupés

Bodywork

See above for trouble spots

Classic & Sports Car – Buyer’s guide: BMW E9 coupés

Engine

Given regular maintenance, the M30 single-overhead cam engine is long-lived but corrosion in the alloy head passages can lead to blowing gaskets, and head cracks from plug hole to exhaust seat. Check for emulsion on the oil-filler cap and overheating: a blown gasket means potentially very expensive engine work to avoid recurrence.

Suspension

Look for leaking struts, broken springs and worn suspension bushes that will wreak havoc with the poised handling. Steering box should have minimal play.

Authenticity

Be meticulous when checking CSLs for authenticity: numbers should match the chassis plate and pattern of spot-welds on the inner wing should be as seen here.

Wheels

These correct 14in wheels are often swapped for 16in; confirm that originals are still with car. All-disc braking system is complex, so check it is in good order.

Fuel injection

Bosch D-Jetronic injection is reliable and all parts are available; faults are usually caused by misinformation. Twin Zeniths on carb models can be overhauled.

Interior

Standard CS trim was vinyl or cloth, with hide a desirable option; CSL had Scheel seats that are prone to sagging. Pieces at sides are unique to CSL and often lost.

Gearbox

Sturdy Getrag four-speed manual ’box lasts well; worn synchros/noisy bearings will only manifest on high-mileage cars. A five-speed Getrag was a rare option.


BMW E9: on the road

CSL is in its element on fast, open sweepers. Roundel in C-pillar – by the famous kink – was a direct crib from 3200 CS

All E9s should feel effortlessly quick and pull strongly from low revs. Sluggish performance may be due to a worn camshaft and rockers; a £2000 top-end overhaul (plus £1000 labour) should put it right, if the bottom end is still strong. Blue smoke, knocks and rumbles are the telltales if it’s not, in which case budget £5-10,000 for a full rebuild.

Inspect for oil leaks, especially from the rear crank seal (about a day’s time to replace), gearbox output flange and diff flanges. Exhaust manifold cracks are common.

Bosch D-Jetronic injection can be upgraded to L-Jetronic if desired. A few owners have fitted uprated ECUs from suppliers such as Haltech to give more precise control; others fit triple Weber carburettors for more power. Some cars have been modernised with later running gear, including engines and five-speed gearboxes from a 5 or 6 Series BMW. If this is done well, these cars achieve prices that reflect the quality and cost of the work that has gone into them.

Automatics used ZF ’boxes to May 1972, then Borg-Warner 65 units; both were strong, but the latter is prone to leaks. Again, later, more sophisticated transmissions do get fitted.

Check autos for clean fluid up to level, and functioning kickdown. Rear axles rarely give trouble, unless run dry (look for leaks); CSLs had limited-slip diffs, which were optional on other models.

Wallowy handling from the rear end is likely to result from worn dampers, as well as soggy rear suspension and subframe bushes. Two servos are fitted to cars with all-disc brakes, and they are not cheap to replace, so test for uneven braking.

The owner’s view

Classic & Sports Car – Buyer’s guide: BMW E9 coupés
John Hudson owns BMWs in both the UK and New Zealand

Kiwi John Hudson divides his life between NZ and London, and has CSLs in both: “I’ve had one in New Zealand for more than 30 years. I have a passion for BMW – it’s the only car I’ve owned that I’ve not had to modify to be happy with it. I saved this one from being made into a racer; I also have a CS and a CSi shell that will become a racer.

“I found my UK CSL seven years ago and spent five years rebuilding it. There was grass growing through it and parts missing, it had been bodged on the sills, had the wrong wheels and had minor damage at the rear, but the inner-wing spot-welds were all original and the interior was still in place. I did 4000 miles in the CSL in 2016, including two trips to Germany. I love driving it; the visibility is amazing.”

Citroën SM (left) and Daimler Sovereign (or Jag) XJC are alternative buys

CITROËN SM

Maserati V6-powered SM was conceived as a sporting DS and was a technical tour de force. Complexity and rust make it costly to restore, but comfort, handling and brakes are superb.

JAG/DAIMLER XJC

Launched earlier, the XJC could have been a serious rival to the E9. Build quality wasn’t great, but it was stylish, quick and rode superbly. Rot has claimed many; V12s and Daimlers are rare.

Sold 1974-’77 • No. built 10,375 • Mpg 12-22 • 0-60mph 8.8/7.6 secs • Top speed 124/148mph • Price new £4315 (XJ6C, 1974) • Price now £10-35,000

 


BMW E9: the Classic & Sports Car verdict

Classic & Sports Car – Buyer’s guide: BMW E9 coupés

The E9 is a quality car that, in good condition, is a delight to drive. But after many years in the doldrums, followed by a price explosion, many hide poor past repairs, swapped parts and identity crises.

If in doubt, check with BMW and the Car Club before buying and avoid incomplete/rotten projects unless very special, or you are an experienced restorer.
