A few things to think about! Thanks guys.
Driving the Z4 slower isn't an option - I've tried and it doesn't work!! My commute is 15 miles each way, with a mixture of 30 - 40 -50MPH roads and lots of stop-start traffic. I've used half a tank this week (~170 miles) as I went out for dinner in the evening at one point. I get better economy on the motorway obviously, but rarely ever do - apart from on long trips where in my 320cd I'd still be seeing 10+ MPG more than I am now.
The 320cd is sorely tempting, as I absolutely loved mine. They're getting on a bit now though, and all examples I've found are high-milers. I might take a look at some examples that have been well and truly looked after, but I was really looking at something with 40k or less on the clock. That said, my yearly mileage is a lot less than it once was.
