The pic isn't clear but it looks like the E3 doesn't have diving board bumpers on it which makes it a 73 or earlier. For the price of a tool kit, you get the Bav, you'll feel the love from your neighbors when you bring it home.
If BMW really loved us they would have made e3 and e9 tool kit clamshells interchangeable. Alas, they don't and they didn't. Lots of other stuff beyond mechanicals could have been interchangeable: it isn't.
I have a brand new, in the bag, e3 clamshell and a few tools. No one wants the e3 shell.
