I see you want a CBX...if you want to get that CBX one day you need to work towards that goal and create a loose plan to get there...what needs to happen to get there?
If you have debt work to get rid of any debt by making sacrifices to live below your means and attack the smallest debt or highest interest rate to leverage the pay down. As you pay one off roll that previous payment onto the next one...over time this can get you out of debt quicker but, you work to get that way.
Being debt free will free you to go places and do things that are not possible when you have those obligations.
Before you do that debt elimination you have to build a savings you can draw on if you lose a job or have unplanned expense. Replentish that fund and don't raid it. Ideally you need to have the ability to weather a period of between jobs 2x what you hope for it to be.
Use cash and keep track by logging what you spend your money on. That is eyeopening when you review that...
CBXes are just going to go up in price, BUT the bike market is very soft and has been for several years now. That is, bike values have not grown like several other things, so prices have increased but they aren't an investment that is wise for many "collectibles". If you are riding it a lot it isn't a collectible...so consider your goals. Maybe you want a nice one but it doesn't have to be perfect. That opens the door to more options and more flexibility. Value is largely based on appearance, keep that in mind.
BUT, I think they need to be cared for and used, ride them don't hide them!
Buy the best example you can find; as rebuilding or restoring a rare bike like the CBX is very costly...that may mean you should save more. Then insure it for an appraised value and have it reappraised every 2-3 years and ensure you step up the coverage to cover a loss if wrecked or stolen.
Build a book on your work and expenses, it will help substantiate investment as well as help keep track of your expenses as well as assist a good appraiser that knows the bikes. You have to find someone who knows what they are doing in appraisals. Some insurance companies will pay stated value claims with no hiccups or hesistance, others are not so honorable. So, research your MC insurance company.
You can date and live life but working all the time you are using your most valuable resource; so don't waste it. If you need to get more training or experience to increase your ability to make more money look at the cost of not doing that or actually doing that...
Have a plan and goals it will help you in life, accept that plans change and Murphy strikes with regularity. There is the old Yiddish proverb, "Man plans, God laughs"
Base your plan on reality and recognize life changes and plans change, what you think possible or is realistic is tempered by reality. It doesn't mean you don't plan, maybe with time you no longer have that goal. Educate yourself on that goal and calculate the costs of ownership and acquisition on facts when possible. Have you ever ridden a CBX?
So, all these ideas you have about what ifs with this girl are quite elaborate and you are wasting a lot of brain cells on these potential fantasies...you don't have a clue what she is like from one or two brief interactions. You may find her intriguing from a distance, but reality may be very different, you are setting up some expectations for a relationship that hasn't happened, is this normal behavior for you? Consider my questions rhetorical and take my viewpoint with a grain of salt.
