The sentence everyone is struggling with :
It could do with (but in this context I think ci sarebbe is future conditional so I’ve taken it to mean “there would be” ) underseal and (it needs) a wheel/emergency tool kit (crik is a jack, but porta crik is the whole shebang including tools and braces as well as the jack) and some retouching to the paintwork.
You may want to clarify whether they intend to do this before you get it or whether that’s what it needs, as “ci sarebbe” could be taken both ways that I have suggested.
Edit: I’ve had a rethink…. the tone tells me it will have underseal, tool kit and some retouching to the paintwork…..
