BMW 7-series

   The BMW 7-series is produced since 2002. In 2005 this car was slightly facelifted. Production of this model ended in 2008.

   There are a number of engines developed for the BMW 7-series and each of them delivers stunning performance. The entry-level 3.0-liter petrol and diesel engines are the best for everyday driveability with the lowest running costs. The 730 diesel is particularly a pick of the bunch. All engines are coupled with a six-speed automatic gearbox.

   The BMW 7-series has an adjustable suspension. Via the iDrive it can be set to Comfort or Sport modes. Despite the car's dimensions body lean is not significant. A speed-sensitive steering gives accurate feedback.

   The 7-series autos are very refined cruisers, but there is some mechanical clatter at high revs and engines are audible, when pushed to the limit. Optional larger wheels also generate too much road noise.

   Looks of the 7-series might appeal or distract some buyers. This BMW executive car is pricey to run, so better stick to the 3.0-liter models for lower running costs. Furthermore these model keep their value better. There should be no concerns about the reliability of this car, however failures with the iDrive system might be extremely expensive to fix.

   This car has a rock-solid build quality. In fact even higher quality standards apply to the 7-series than to other BMW cars. The interior is appealing and has a nicely designed and integrated trim elements. However some controls are poorly positioned and the iDrive system, using a single knob for hundreds of functions, is very complexed and distracts attention from the road.

   The BMW 7-series is a big car and an extended-wheelbase version offers even more space for the rear passengers. The boot is quiet large, but it is poorly shaped.

   The BMW used a number of safety features for this car, including a class-leading active safety technologies. Computer controls force and speed of airbag deployment. There are also seatbelt force limiters for all seats. Stability- traction- and brake-control systems are standard across the range. The only downside to security is the lack of marked windows.

   The 7-series comes fully loaded. Even the base models come with climate control, CD changer, automatic headlights and wipers. Alloy wheels, power front seats, cruise control and parking sensors are also standard. More expensive models add larger alloys, built-in phone and a satellite navigation. An extended-wheelbase version comes with a self-leveling suspension.

   Advantages: Stand-out looks and plenty of gizmos inside show BMW is not afraid to try new technology. Superb handling.

   Disadvantages: Looks stand out too much for many buyers and technology can be hard to get to grips with.

   Verdict: A high-tech statement, but too much for some.

   Also consider: Audi A8, Mercedes-Benz S-class.
