whoa thank goodness they came through!
lucky man, a small word of advice, in my experience going to any 'main dealer' regardless of marque is not worth anything. SGT are great but they charge enough that they should be great!
always take your car to a reputable independant specialist, ask on here to see who's got rep near you. I found someone through word of mouth and am very happy, short version, he consistently charges much less than dealer and even the other indy near him,, he even throws in mini freebies when he has time, like reparing my wiper motor for free and not charging for a new one!
