Hello everyone,

Im currently looking for a xj40, and got lost on suspension question. People on the internet claiming that SLS (self leveling supension) is nightmare and should be avoided if possible.

So i have got question ? Wich models were made with sls suspension and wich models werent.
I assume that cars made after 1990`s (3.2, 4.0 engines) have normal suspension, and cars that were made before (2.9, 3.6 engines) have SLS suspension wich should be avoided.
Ty for answers
