There aren't too many surprises with a 7 Series. You know it's going to be beautifully built, great to drive, understated and well equipped - at a price. You'll get all the luxury and gadgets you could possibly want, and then some. Try radar parking-sensors built into the back bumper of some models. Even on the base 728i model you get intelligent traction control (ASC+T), leather seats with electric memory adjustment, alloy wheels, ABS, a six-speaker stereo, twin airbags, an anti-theft system with immobiliser and all the usual executive features. If you really want hi-tech however, see if the previous keeper has delved into BMW's amazing options list. There you'll find everything from steering wheel heating to automatic boot lid operation. There's also a tyre pressure control system and a Climate Comfort windscreen that reduces interior temperatures by up to 10 degrees C. You could even have an Active Seat, which moves either side of the seat squab up and down by 15mm to provide a slow lateral tilt of the pelvis and reduce fatigue and back stiffness. Safety-wise all post 1997 7-Series saloons benefit from what BMW has labelled 'ITS' which, believe it or not, stands for Inflatable Tubular Structure.
This potentially life-saving device is a cylindrical air bag that protects the head in an impact. It works in conjunction with the existing driver, passenger and side airbags that are designed to cushion the face and side of the body, respectively. All of which could come in useful if you're the sort of driver attracted to the Seven's sportiness - often lacking in some of its rivals. You can throw the big BMW around and it won't bite back, unlike its predecessors and it's good to know that safety is second to none.
Once you've chosen your engine, is it worth choosing manual or auto? The auto boxes are good, and despite the sporting pretensions they suit the 7 Series better than the manual box. Long wheelbase models give a few extra inches of rear legroom, but don't feel as balanced to drive as the nimbler regular cars.
Just about the only problem reported with the 7 Series has been sticking valves on 728i models, caused by running them on high sulphur petrol. Most of the cars you'll come across will still be covered under warranty, and the service history should carry the stamps of franchised dealers or well-respected specialists. When paying this sort of money you should expect the best and negotiate big discounts for tired interiors or less than cosmetically perfect bodywork. Avoid dull colours and be aware that V12-engined models won't be so easy to sell on.
(Approx - based on a 1994 730i) A replacement clutch is around £130, while front brake pads weigh in around £50 and an alternator (exchange) roughly £230.
It's no wonder that when McLaren were looking for the world's finest engine to plumb into the guts of their F1 supercar they chose the BMW V12. It's an absolute beauty, and is one are where BMW has Audi and Lexus firmly by the short ands curlies. Under the bonnet of the 750i lies a 5.4-litre 326bhp engine which, on the autobahn, is restricted to 155mph.
Only marginally less impressive are the V8 740i and 735i models. For most, the 235bhp 735i will probably suffice. There's a huge amount of pulling power and sixty from rest is just 8.4s away en route to nearly 150mph. If that really isn't enough, the 4.4-litre 740i develops 286bhp, good enough for sixty in 7.1 seconds on the way to a top speed of 155mph which, like its boardroom brother, is artificially limited.
For once, however, saving money needn't mean curtailing your fun. The 730i and 728i models never feel manifestly underpowered, and the 728i could just be the secret pick of the range. Under the bonnet, you will find the 2.8-litre six-cylinder engine also used in plusher 3 and 5 series models, as well as one version of the Z3 roadster, capable of a top speed of 141mph and able to despatch 60mph in just 8.6 seconds. When you consider that the 735i could reach 60mph in 8.4 seconds yet would return 26.9mpg as opposed to the 728i's figure of 31.7 you'll understand our admiration for the 'baby' Seven.
Ever wondered why so many used car dealers drive a 7 Series? It's because they know a good buy when they see one. The Seven has suffered at the hands of the Mercedes S class, Audi A8 and Lexus LS400/430 models and as such makes excellent value as a used proposition. Though the slightly raffish image may put some off, don't be fooled into thinking the big BMW is yesterday's news. Understated it may be, underdeveloped, never. If you can afford it the 4.4-litre 740i is all the car you'll ever need, but the star of the range remains the relatively rare 728i.
