My son-in-law has a new VTX 1800. Aside from being better looking, more reliable and less expensive, it always gets a lot of favorable attention from the good HD folks.
I know of a VTX rider who was at a H-D dealership looking at the new bikes when a salesperson asked if he wanted to trade his 1800C -- "Well, I am getting older and probably could do with a a slower, poorer handling and heavier bike"
Salesperson was not a happy camper after that
I don't know about being better or more reliable, but it gets kudos from bikers, because it's a good bike. The VTX is a fine machine in just about every respect. I have a buddy who owns the 1800, and it's served him well, although not as reliable as my Harley. He had to have a stuck valve replaced at under 20,000 miles, and I'm still going strong at 35,000 with no real failures.
