THE relentless revisions to the BMW range continue unabated with the recent arrival of the latest 6 Series, X3 and 520d models and the forthcoming new 1 Series coupe range.

In a relatively short time the prestige German brand has gone from niche market player to mainstream mogul, with the 3 Series out-selling even Ford’s Mondeo.

The entry-level 1 Series has emerged as a success beyond even the expectations of BMW itself, with prices from £16,390 for the 1.6-litre petrol model.

There are half a dozen different engine choices encompassing petrol and diesel models with different transmissions and a combination of 155mph performance and 60mpg economy.

The larger 3 Series range encompasses saloon, touring, coupe and convertible body styles with a similarly wide choice of engines.

There are also the legendary M Series versions and some cracking diesels capable of 155mph performance and 35mpg economy.

The family size 5 Series range also includes an ultra high-performance model in the M5, with a price tag of £64,600 and impressive acceleration to 60mph in just over four and a half seconds.

The 5 Series comes in a choice of saloon and estate body styles and a wide range of engines that include some awesome diesels.

There is more of the same in the larger 7 Series saloon, which offers a further choice of long wheelbase models and prices of up to £85,000.

On the sporting side there are the recently-revised 6 Series coupe and convertible models plus the Z4 coupes and roadsters.

SUV models include the X3 and larger X5 4x4s, with prices from £30,915 for the X3 2.5 SE rising to £53,500 for the 150mph X5 M Sport with 4.8-litre power.

Both models come with diesel options, which in the case of the smaller X3 start with the standard two-litre unit generating 150bhp for a top speed of 123mph with economy averaging about 40mpg.

The X5 also comes with an oil-burning option, which is a three-litre unit giving 130mph performance and 32mpg economy.

All BMWs come with a three-year warranty with unlimited mileage and although they may be more expensive than many of their mainstream rivals the fact that they invariably hold their values better makes them a sound investment in the longer run.
