I am looking to buy a more upmarket car for daily use. I prefer estates, but not essential, and again prefer diesel to petrol. Thinking about a Merc E320 CDi. Any suggestions?

Previous E Class not a patch on previous 5 Series.

Go for a nice E39 530d Touring. Described by many as, in its day, the best car in the real world and more recently 'So good its rivals simply gave up and went home'.

Certainly look at the Mercedes and BMW, but also try to test-drive the Audi A6 Avant 3.0 TDI and the Saab 9.5 estate, also a 3.0 TDI. Perhaps a Jaguar X-type, although the only diesel is the 2.0 / 2.2 Mondeo unit.

If you want lots of space, the Volvo V70 has many fans, and finally there's the Honda Accord Tourer,
