With mine it varies, if you use your private car you get lots, i.e. 45p a mile but can only do that if you travel less than 10k pa on business.
On a company car they pay all incl fuel but charge me 11p per private mile (or 13 when I use the pool car due as it’s over 2l).
Think taxwise DSG works out around 30£ a month more for me. Doing 30k-45k on company business a year around the SE it was worth it for me, just for stop and go on M25 it is worth it (just turn ACC on).
Up near where you live I imagine roads are a lot clearer
Think the most it will cost you in tax atm is £300 a month if you pay 40% tax on the car. Still a lot less than what it’d cost you privately (as much as I loathe giving it to the tax man who will hand it to the incompetent Tories and NI numpties).
I wouldn’t go back to a manual as my daily car as long as I can get a decent auto box. Though even as a fun car I like my DSG GTD, probably faster than a manual too.
If I really wanted to save tax I’d go for a fast medium van with fixed BIK or 1.5dci Dacia with low list price and negligable BIK
