Who moved from XJ to a Liberty

3.7 v6 is ok, but it will not forgive any over heating. Same as any aluminum head engine.
The 4.0 xj is a tough engine that can take abuse, 3.7 is a good engine if taken care of.

Never driven a kJ but in the Commander the V6 is decent. Although that heavy body really wants a v8. Still the 3.7 is powerful enough to move it well.
