Just to answer your original question Jon, how often do you scrape/ bottom out .... erm well Multistories carparks are now a no go, high streets, garage ramps, speedbumps, some drives, dropped kurbs roadkill in the road, humpback bridges are all off the route, so no I never scrape, purely because I dont take it to any of these!
Would I change it ..... HELL NO!!!! I love it!!!!
