Hi, and thanks for your time. I am about to take our 1.4LS Astra for a 20,000 mile service, can someone tell me some of the Major/Minor Items that should be checked by the garage, I usually do all my own preventative maintenance, but I've got to take it in for the Warranty, but I will be checking it out after I get it back to see if the Items are done ,,and will let the group know what happens. Thanks
