95 or 97 will be fine, but you may loose a bit of timing with 95 and in turn it can end up less economical.

I think your doing the false economy thing
Agree with Scott, no problem running 95, but most people will run their scoob on the best fuel available, even on a standard uk car, the highest ron is better than the lowest, simply because you gain power and a slight gain in mpg because it burns better, otherwise your ending up using more 95 ron and paying a similar price in fuel as you did before, so you may as well stick to the good stuff
