  Open sources record no battery, motor or power electronics faults for this version, and it falls outside the production period of the module recall (up to March 2022). There is little long-term usage data.^[1][2][4]

Buy: No known serious faults, or they have already been corrected, in this version. With caution: Worth buying if something specific is verified: history, a replaced part or a completed campaign. Avoid: High risk of a serious fault that is hard to check for or prevent.
