uh oh, now what

Another bad thing with bringing over $10K in cash to the bank is you instantly draw federal attention.
I sold my vette this spring for the I don't want to sell it price, neighbor knocked on my door and said he had a friend that was interested, I told him the price and it was firm, the guy showed up within 45 minutes.
This was on a Sunday, so I said cash only, the guy showed up with the cash the next day.
Signed the title over to him, and he had it picked up on a roll back.

When I bought my wifes CJ-5 it was kinda spur of the moment over the week end thing.
The guy accepted a check for the full amount and gave me the title, but he kept the jeep until the check cleared the bank, then he delivered the jeep to me.
