As a bit of a cynic I believe most if not all options you add to a new bike add no value at all come trade in as they base the value of your bike on the model, it's age, condition, milage and service history. The options are really just for your convenience and just benefit the next owner, make your old bike more attractive to a similar model without them to prospective buyers and of course the dealer makes more money on the original sale with those extra options too. As you say the house wins.......The difference in trade-in money was only a few hundred quid, and I'm not convinced that I'm seeing much return for the several thousand I spent on options. maybe the message is - whatever you do, the house always wins.
