Tee hee, in theory? or in practice?
Seriously tho, YES you have a capital gain, and YES you have to pay taxes on that capital gain.
And for the people who are gonna ask why you can't get a loss, thats because there is a specfic rule saying you can't claim loses.
Basically government only takes upside on the capital gains/losses associated with what is considered "personal-use property" which includes cars and bikes and boats etc.
