well, whether or not it is worth it is a question only you can answer. but for your $12,000 + you're gonna get a bigger engine, much nicer paint job, 75 watt per channel amplifiers, mirror chrome chisel wheels, hd ventilator a/c, LED passing lights, better exhaust (subjective), wrap around led run/brake lights on the tourpack and dual control heated seats. plus some other chrome bits.
if you were to add the items individually, it would come up more than the cvo cost wise. but, the question becomes, would you add all those things? or only some of them?
if you look at the limited edition paint sets, with the extended saddlebags, and tourpack, they run about $10,000 for the complete set.
course, you also get the improved resale value of the cvo vs the limited which all your add-ons don't really increase the book value of the sale (if thats a consideration for you)
