After riding a demo bike from my local dealer, I was hooked. However they couldn't or wouldn't do a decent price/deal so I bought mine new (in June) from North Oxford Garage. I had various extras including ABS, H Grips, full computer, clear indicators, vario topbox and a full chrome exhaust all for less money than the local dealer came up with for ABS and H.G only. The bike was also delivered to my home with a full tank of fuel. The first service was done and I was provided with a loan bike free. (F800... made a change).
The chrome exhaust should not turn brown. It looks great now it has blued the down pipes. I would certainly go for a chrome exhaust unless you intend to fit an after market item.
