Thanks Revd. Yup, have heard the poly vs OE argument before, for many bushes not just the ones we’re talking about.

Amusing that you say that Solihull weren’t happy with all aspects of its performance, given they didn’t seem to give a fig about the Defender’s performance for the last 20+ years of its, ahem, ‘development’. More likely than not, the performance they were talking about was in the ‘how is this expensive to build’ vehicle performing on the accounts department’s spreadsheet. In that regard, poly would have been a far worse performer than the parts bin downstairs with thousands of OE bushes already in stock….
