I've only just caught this thread - what an awesome build!
It's tough to see these things through sometimes, especially like you when you've peeled the layers back so far in order to do a thorough job!
Another thing that doesn't help is not seeing the car too often. It's easy to forget how impressive how impressive something like this is in the flesh. My last build was a driveway job, so got covered up between bits of work, and even that was bad enough! But peeling back the cover always brought a smile to my face and renewed my enthusiasm.
What we all need is a centrally heated double garage so we can pop in over a cup of tea and have a gander!
Keep it going mate, it'll be worth it in the end.
Cheers
