Hi MR T and welcome, I was in the same situation as you, I was torn between the Xr5 or the MPS,
What sold me was the MPS has a LSD and the upgrade path to 200kw ATW is cheaper. Tune and DP should get you there where in XR5 was a lot more, torque steer is overrated in MPS, A REM really helps with torque steer.
Whith that many KM I would get a mechanic who knows the MPS to check it over because they can suffer from smokey turbos, timing chain and vvt actuator problems
