Welcome JJ.
Have you test driven one? The first thing I would say to you is get that out the way. If you dont like it then theres no way you're going to get it anyway!
On the more practical side, I do a 75 mile round trip, 5 days a week for work - equating to about 20k miles a year. I get paid 37p a mile and that does cover all my petrol and most of the servicing/maintainance. I say most as I tend to go for upgrades when it comes to replacing stuff, and 37p a mile doesnt really cover it! I get on average about 29 miles to the gallon and that does include a bit of A-road fun on the way home. So as far as the money side of it goes, I think you will be covered if you drive sensibly. Also the car is great at munching the miles. A couple of weeks ago we had one of our North Wales drive outs and I covered over 600 miles in 3 days and felt no worse for wear than if I had just driven to the shops.
Get out for a test drive and see if you like it. Certainly dont let money put you off it
Oh also, dont be put off by the heavyish steering and clutch. You get used to it in no time and other cars feel light and flimsy afterwards!
