Passing an MOT is not an indication a car is in good condition imho.
I would go for a service with an approved dealer or specialist garage, they will more likely check out the suspension system in more detail and advise neccesary repairs.
You can quickly check the suspension by bouncing it and listening for knocks or creaks. A lot of bounce indicates problem.
It's also fairly easy to get underneath the rear and take a look at the bushes and arms for wear, specifically check the linkage on the subframe for wear, as this can end up the most costly if the frame is damaged.
To err is human, but you need an Alfa to really screw things up!
The road to heaven is paved with old Alfa's.
