Didn't realise you still had yours Stu, I though the diesel took its place!
The Diseasel is better in many respects so the M only comes out to play once a month as I just do too many miles to justify its fuel economy sadly.
Had the Derv 18months now and put 40K on her already.
She is pretty though and with 620ftlb and 370bhp it makes the M5 feel slow in 95% of situations. Sad - But true.
