BMW 4 Series - petrol or diesel?
I want to buy a new BMW 4 Series. Taking into account I will do around 12,000 to 14,000 miles per year, would you recommend the petrol 428i or 420d diesel?

The 428i will be the more fun, more satisfying drive. But the 420d should do 55 - 60mpg, which is not to be sniffed at.

Our 2004 Jeep Grand Cherokee is tired and we fancy a Mercedes-Benz ML-Class 3.0. We're wary of diesels because we only do trips of about 10 miles. Should we be wary? If so, what's a good petrol alternative?

Handles as impressively as you’d hope, handsome styling makes the newer 4 Series look fussy, wide range of strong petrol and diesel engines, plenty on the used market.
