I connect my CTEK to the under hood terminals with the alligator clips then drop the hood all but the final latch. Not the most convenient solution but always reliable.

The MSX 5.0 looks like it will be fine. I have the MUS 7002 as @Reanard does. Works fine for my several cars & battery types. It has a Normal mode, a "Snowflake-symbol" mode, and a couple of others for reconditioning or whatever. The Normal mode is for regular 12v batteries. For the Porsche with AGM (absorbent gas mat) batteries it is recommended to use the Snowflake mode.
