I was on one of these Solars Mark. Couldn't find anything wrong with it, I travel on Euro 3 B7RLE Eclipses a few times a week and I actually preferred it, you don't hear the suspension clunking over bumps like the Euro 3 B7RLEs do and the gearchanges are much better. In defence of the Volvos, they are owned by First! The Bus Éireann B7RLEs are excellent buses and I would prefer one of those to a Solar.

Not sure what kind of K230 you went on, but there is absolutely no comparison between an SL (CK230UB OmniLink) and a VWL of any description, the KUB chassis is definitely not as good as the Volvo one and then there's the well known bodywork problems on top of that.
