When I replaced the box, I found the old box stamped with double chevrons and the code 9601. As the car was built in mid-January 96, I take this to mean 1996 week 01. If so, the original box has lasted more than 13 years and 93,000 miles. Is this a record? The really annoying part was that the rest of the box was as sound as a bell
A new genuine Citroen box was 50% more expensive than a pattern part and I reckoned it would be expecting too much for the car to last another 13 years of more or less daily use.
Strangely, the best deal on the exhaust (from stock) was through our local Vauxhall dealer
