i haven't done all the maths, but i cover in excess of 300 miles a week, every week. i put as much as 6 tanks of Optimax in Scooby a month (@ now over £40 a tank). so i bought a Pug 306 DTurbo a few weeks back (500 miles per tank @ £50 a tank with briskish driving).

yes i added to my insurance, will have to tax and m.o.t both cars next year and paid £2700 for the car. but its saving me approx £120 - £130 a month. this more than covers tax, m.o.t and additional insurance premium and leaves me around £250-£300 quid up on the year. meanwhile Scooby gets less wear and tear and is at less risk of damage for a mundane daily journey in traffic in which i get no particular enjoyment.

when i get back into Scoob at the weekends its a real joy. the Pug is frugal and fun on the right road. its extremely chuckable and has more than ample pace for the daily grind. so i do see a financial benefit to owning it - i get the additional benefit of a load carrying, park anywhere (lower theft risk than Scoob) daily motor.

plus if Scooby goes in for work longer than a few hours, there's no car hire (assuming a courtesy car isn't provided) or public transport inconvenience - i hate public transport and use it as little as possible (like never, unless flying somewhere)!

 

my fuel bill is currently £160 a week (always, always optimax™).
daily commute five days.
firm gave me a fuel card for optimax and oil
total fuel bill for the year is 22% of £2200 which is nice!
