Not a bad score mate, looks like it does not need much to be quite a respectable first car.
I agree with your comments about power. The old saying " You are better learning to drive a slow car fast, than a fast car fast" rings true. A stock or near stock KE70 will be a great learning curve to start with.
No good to hear about your hit your wheel arch, but I think this should not stop us building nice cars. If we all lived in worry of being hit, no nice cars would ever see the road. I think show quality streeters should still see plenty of road miles.
A few steps like having full comp with a suitable company like Shannons, and minimising your risk where possible are all that's necessary. We should all observe for idiots around us on the road, park in sensible areas to avoid shopping trolley dents and drive within our limits.
