Yeah it depends what you mean by "ultimately" you want to fly to European destinations. If you mean straight after you get your licence then £10k pa is realistic, but loads of people dont spend anything like that by being more modest in what they fly - LAA types or microlights for example. You can fly a top of the range microlight round Europe, but its a strictly VFR good weather machine.
So it all depends on your motivation - what you are going to get most value from
