Advice on buying a SCOTT SUB Sport 10 2014
Scott is a fine brand. The most important thing is how it rides and fits for you (this is a highly personal decision on your end). 

For a 90 mile ride though, you may want something with drops (with a relaxed geometry - something like a Trek 520 wouldn't be bad for this purpose, for example) or a flat bar with bar ends or a trekking bar or something for multiple hand positions if you're taking the 90 miles in essentially 1 or 2 shots. However, I'm not familiar with the particular European terrain, so I'll defer to the Europeans.
