future value of classic performance cars,when to bail out, before the crash?

The next 3-4 years. Watch the student loan bubble. NEVER use a car as an investment.
BINGO. The Millennials are screaming bloody murder about their student loan debt. They borrowed $20 per year and didn't work at all because they wanted the REAL college experience. Then they graduated with $80K in debt and are upset because the $100K per year job they think is owed to them isn't there. So they don't think they should have to pay back the loans. Mark my words, WHOEVER RUNS AGAAINST TRUMP NEXT TIME WILL HAVE STUDENT LOAN FORGIVENESS IN THEIR PLATFORM!
Plus, I TOTALLY agree that I am not in it for the money.
