Thought it wold be good to share my experience with this workshop here. My 3 year old Peugeot was giving me problems with the transmission and the warranty has ended!
When I went back to Autofrance for the gearbox repair, they quoted me and exorbitant sum! On the recommendation of a friend, I went ot Khang, which quoted me only about half as much.
Most importantly, they cured my jerky gear change.
