Expert Opinion

One of the more powerful variants in the already sizeable 6 Series range, the 645 is a classic 2+2 coupé which comes with a hefty 4.4 litre V8 engine which, although surprisingly quiet, makes it a car with serious gusto. Style-wise it is sleek and elegant, despite its size, and like much of the German manufacturer's range is modern and eye-catching without being an eyesore. 0-62mph in 5.8 seconds and a limited 155mph top speed show its speed credentials to be as impressive as its refinement, while ride and handling both favour the controlled-yet-responsive feel seen in the rest of the 6 Series. Also being surprisingly affordable, the BMW 645 is one of the stand out models in an already impressive range, and having been discontinued, makes for an excellent value used option.
