LOL, the guy building a $15K race engine, just because he wants to, could have more investments and financial resources than you will ever have....on what grounds do you make those opinions about the OP or others? You know nothing about their current financial status..?
For what reason are you attempting to enforce your thoughts with regards on when and where to put your money?
Like i said before, a guy who has a big mortgage on his neck and is struggling to get by will not pump his last savings, or loaned credit in his "10 sec pro street" car.
Even if he does, which is obviously not wise, it is up the person himself...
The question he asked is, what others would do with this engine he bought, so if you had the money to spend and the availability to do so, what would you build?
For a change, just GIVE YOUR OPINION on the question that was initially asked?
since you don’t know me and you assumed a lot of incorrect things but then I saw that you were just concerned. I wanted to reply so you could rest easy at night. The main thing to remember is man can make his plan but God directs his steps or in other words God is in control! The second part is my financial stability. I won’t go into actual numbers but I will say that at only 43 years old I have made a considerable amount of money buying and selling financial service industry based companies. I am a fiscal conservative who puts away more money than I spend. I donate 20% of my income to my church and other various social service organizations. I am heavily invested in a private company that returns Ponzi scheme like returns! So all though I appreciate your concern for. mine and my family’s wellbeing, know that other than a complete collapse of the US economy, we will be okay.
