I looked at the 07 1200C and bought the 900 Classic. I like the looks of the Fat Boy and bigger bikes, and the 900 classic has that look at 1/3 the price. The 900 Custom is more like a mini softail standard or wide glide.So, here is my deal:
I recently had an accident with my 2007 HD XL1200C I bought in 01/2007... while I am waiting for the adjuster, I believe the bike will be totaled due to frame damage. I passed the MSF in 8/2006 and I am fully endorsed by my state.
At the time I bought my first bike, I was not commuting every day. I am now. Finding after market side bags, etc is high on my list of needs.
If bags are in your future, get the 900 Classic LT which comes with bags, sheild and sissy bar, which makes it kinda like a mini heritage, only with belt drive instead of chain.
You could also look at the Nomad which has hard bags, like the road king only with more capacity, and low maintanence due to it's shaft drive.
