You are right though family life will suffer, I won't see my family much on the late shift weeks
Are you really going to get over 45 mpg?
All good points
I have had a quick look and taking into account increased NI, student loan, pension and car insurance charges probably £4,000 better off, then say £2,000 extra on diesel so circa £2,000 a year in my pocket so not a massive amount but a step in the right direction I think for my future prospects.
