I'm going to be purchasing a Astra vxr over the weekend, I'm getting a full service and have been told the car needs stem seals and retainers doing! Iv asked a few of my mechanic friends and they said they won't be able to do it! I'm hoping to get this done before japfest at the end of the month!! Is anybody on here able to fit them for me as close to sunbury upon Thames as possible👌🏻 Name your price!
