No, they're not the right wheels. I think it would have had steels with body-colour caps (or maybe the one's Howard suggests).
Is the reg number included? No mention....
Dependant upon what needs doing, it probably isn't worth restoring. Refurb, yes, but not anything major.
If it was a 500, then it might be worthwhile, but even then you're probably not looking at more than £9k in pristine nick. SLC's are not as popular as SL's and will be more expensive to rebuild.
