I have a new Roadster on order ( if they ever get the new engine sorted!).
The first thing I will do is check the run of the battery cable over the battery brackets ( that did for my last one when it shorted out :-(
Next, I will dismantle the headlight assemblies & treat all the chrome with Rustguard as I found these to be prone to rusting.
Next, I'll remove the front indicators & make sure the back is sealed. I had to replace both assemblies due to water ingress.
Then I'll stop faffing about & get driving the thing!
