It has worked out well. Local Subaru MD quoted me £460.00 for a wheel and said they were ‘unaware of any other alternative other than a Road Hero Space Saver for £245.00 but don’t worry, you’ll be fine with the emergency repair kit’. So I asked our local village garage and he told me exactly what to do, checked it was exactly right before I bought it, tipped me off about the spigot ring, fitted and balanced the tyre, all for £15.00. (Note to Subaru MDs - this is called customer service ...)
