AVO adjustable shock absorbers do make a difference and they are not expensive. If the car still has the factory fitted items, they may be MOT safe but are well past needing changing. On our current (2014) car, I replaced the standard shock absorbers at around 20,000 miles.
Good luck.
Phil is very knowledgable and helpful - pleased you were able to speak to him.
