I typically fill up at 200 miles +/- 10 miles and I'll get 58 litres in.
220 is doing well. If I don't know where the nearest shell station is and I'm at 220 miles I'm concerned to say the least.
I very much doubt you'd lease one of these cars at £450 inc. VAT - that's more likely a +VAT figure.
I can't remember the details of the Performance Pack + PPPlus; lik I say, the LSD is a must. I wouldn't be concerned with paying for the higher engine output at factory level, similar figures are available with a map at much cheaper cost.
Gone but not forgotten:
325i M Sport (E92), Black Sapphire, Coral Red Dakota, 19" 225's, Seat Heating, 6FL and de-badge
Replaced by 6.2 litres of AMG powered C class.
