I test drove a new Puma when swmbo considered one. The salesman was quite disappointed when I pointed to my battered looking 200tdi 110 in the car park and said that the puma was no quieter, no quicker, no more comfortable, no better built and simply just no better than what I had arrived in. I was amazed at how little improvement there had been.
Have a think about what would make your 110 what you need. Better the devil you have rebuilt than some unknown IMO Phil. Theres lots you can do to make them more comfy, run better and quieter etc.
