Hi
@Zephyr . Do a rebody for sure but start it with your eyes wide open to whats involved and how much you want to do, and how much to palm off to mechanics or a body shop .... but you're asking the right questions.
In my opinion it comes down to this
1. What do you want...a replica or a car you want to build in you're own style. A replica ia good...if the build is good. If youre building your own car style that draws influence from other cars then you have mire freedom in my view. Thats what I'm doing. I dont want people to see mine as a replica or homage to anything....its just my car in my style and im very happy about that. If you want a replica so be it but be prepare for comments of comparison
2. Approvals.. rebody in uk is needs not IVA check...something like a 356 with shortened chassis will need .ore approval/iva etc
3. The kits vary in quality and youll end up working the kits to your body. The Tribute ones need a lot of work but if you buy knowing that its fine. I did and i like the bodyworks side of things. So its a lot of hours but it depends on the finish you want. Be your own critic.
4. If attached to the body correctly then should be no rattle. Ive only driven mine a short distance so far but no issues whatsoever.
5. The rebody bmw drives great and with solod bmw base chassis its great. Ive built lots of beetles in the past and while they are fun they are not to bmw standard or handling. I looked at 356nl kit butbwent bmw tribute
6. Prepare for a lot of work, but nothings rocket science.
7. Enjoy it , and enjoy building it. I really enjoy seeing it come together
You'll get a lot out of doing it...more than a boat (and I like sailing too) in my opinion. It will frustrate you, obsess you, spend your money for you...but that's all.part of the fun.
Set put a plan and go for it I'd say..I speng a year researching mine and read loads of forums etc and then went for it
What have I learnt.....things don't happen unless you make them happen, and so what if you make a mistake on the way...it just takes time and energy, and if you have that then go for it.
I got mine home this week and it's great fun but I agree with Duncodin ...enjoy it while you build it
I look forward to seeing your build if you do it.
