Zeds ain't cheap to run. At all.
If you're really gonna be tight on money as you are setting up again back in the UK, are you sure you wouldn't be better getting a cheaper car for a few years till you're settled.
At over £100 to fill a tank (with V-power or equiv), 20mpg cobined (more likely 15mpg round town,) plus insurance, plus tax, plus your finance, and then the cost of pads/discs/services on top...
If you're ok with all that, then go for it. As I say, I'm not trying to insult you.
But if you can't stretch an extra £750 for Viks car (which on finance over 3 years is only £20 extra a month), are you sure you're in a place to run a 350?
