I got mines changed last year, think there is 8 in total, including the service total bill was £561 so if service is normally £200 then £361 is the cost of getting the bushes done..... may be a bit of wiggle room in that price as can't remember whether there was anything additional on that bill from the regular service items (wiper blades, bulbs etc). That was from a SAAB Indie garage and we fitted the regular bushes because I've heard the plastic ones harden the ride and if the originals lasted 10 years and 100k then I'd be happy with that again.
