IT'S hardly appropriate to describe a $170,000-plus luxury saloon as "entry level" but that's the least you can pay to sample the delights of BMW's latest 7 Series. The nearly two-tonne 735i asks a lot of its 3.6-litre engine, but it manages well, what with 200kW and a surprising serve of torque. In fact, most passengers are hardly likely to notice the 735i buyer has invested a good deal less in automotive indulgence than the bigger-engined 745i. The car is dynamically outstanding, extremely well equipped apart from the lack of a sunroof, and as comfortable as you'd expect a flagship model to be. There are two things to get around: the mysteries of iDrive, and the quirky styling.
