It's a good deadline to work towards. Just make sure you're done with plenty of time to do some shakedown work on it. I did / helped on an engine rebuild on my Cossie and landed up with melted boost hoses, loose turbos, and finally a snapped inlet cam while I was there. Was a lot of hassle.

Make sure it's all good to go before you go!

It's a great trip, lots of laughs and socialising - plus plenty of nice cars being ragged to the bitter end!
