As I had read a post on the Forum recommending Dorys Garage in Sway, New Forest, I took it in this morning ; and picked it up this afternoon. No horror story of rip-off Citroen repairers here:-
Supply and fit two rear spheres
Fit anti-sink sphere (I supplied)
Adjust front and rear ride height
Top up LHM (1 litre)
Total bill (including VAT) £115.26
Although the garage is in the New Forest, it is just 50 yards from the Rail Station with trains to Southampton and London.
Garage phone number is 01590 683432
