I drive 400 miles a week - commute & personal motoring, more if I go anywhere at the weekend. Car has a 60 litre fuel tank, in summer my weekly commute is easily achieved one tankful of petrol, in winter it's "tighter".

Whatever you choose consider how often you want to be filling up with fuel, so many modern cars come with puny little fuel tanks, whilst they be more fuel efficient their range will not cover 450 miles a week.

Car is very comfortable, lots of nice toys, if you are happy with the Fiat I'd also suggest running it into the ground before replacing it, unless you expect to spend more than the cost of the replacement in maintenance costs.

As well as PCP , still worth investigating PCH - some amazing deals around even with your mileage

Try and make sure you remain within warranty limits and probably best to take out GAP insurance (not from dealer) of some sort.

I have done a longish commute for 20+ years and cover about 16k miles/annum (not as long as yours though) . Personally I prefer to buy V cheap (nearly new, end of model etc...) and simply throw away after 10 years. In this time despite my mileage my "capital" spend has always been less that £100 month (last car was a Skoda Superb, paid £8,200 at 18 months and ran for 10 years - aka £70 month - Then bought another for £10k at 14months old which hopefully will take me to retirement)

In addition, look at crash protection (that's why I buy big!) - I've been lucky but have witnessed some horrors during my commutes.

Also consider other costs, with that mileage such as insurnce , tyre life/cost (can be significant - I specifically pick tall profile tyre models, much cheaper and last many more miles)

Almost ignore car tax costs- with your situation it's the least of your worries.

Good luck

PS I agree with the above. A small fuel tank can be a pain (fill up about twice a month now, used a 1.0 Polo at the start that liked a drink and had a weeny tank that I filled up twice a week!). My last Superb did over 650miles between refils (50mpg). I've moved back to petrol and get 550 between refils (smaller tank and 46mpg)
