Quick follow-up, in case anyone cares or is watching this thread:
* Boss did not drive the car in to work today, as it's supposed to rain here this afternoon, and possibly not gently.
* Turns out the whole "numbers matching" thing was HIS wording to ME, NOT the sellers, and the mistake (and/or confusion) is due to some miscommunication between HE and I, and is NOT on the seller.
* He said the seller claimed the engine and driveline is "date code correct", and he has pictures that show (prove?) this, but here's the kicker: He (my boss) doesn't care about this, as he loves the car and is just going to drive it and enjoy it!
* He says the only changes he's going to make on the car is replace the black top with a white one (which was original color), and in the interest of safety he wants to install power disc brakes on it over the winter.
If the weather holds, I'm looking forward to seeing the car in-person on Wednesday!
My apologies to all for any mistakes I have made.
