XB 4 WHICH ONE TO AVOID

[gromit]

XB 4 WHICH ONE TO AVOID, looking to buy a used XB4 and new to X-ray is there any of them that I should avoid. I ask as heard rumours that certain years were not so good.
Cheers

Depends on your budget really. The 18 and 19 were and are still very good cars, 20 was reported as not as great. 21 fixed some of the 20 issues and the 22 added the 21 with some extra goodies.

What are the main differences between the ‘20 and ‘22.

Is it worth buying the parts to update?
