Obviously been put on wrong on the front. Definate inconsistancy. Spoke with a friend who was serious about cars as I was back when the S1 came out - he said he never saw them with rear overriders. According to a source at the RSOC there were allocation problems on the production line, hence some cars had overriders thrown in the boot. Then the dealers nicked them for the parts bin!
All the cars got front ones, hardly any got back ones.....
Supposed to be on according to all brochures though, just a cock-up/shortage on production....
