30 miles each way, 25 of which are on the M25 between 22 (just before the M1) and 15 (M4) which usually results in a 75-90 minute crawl in the mornings. Evenings are better at around an hour.
Tool: BMW M5 5.0 V8. None of this "omg I do a few miles must get a diesel" rubbish!
Including persional miles I've done about 12,000 miles in 5 months, so probably looking at 28,000 miles a year.
