I'm getting the idea that there will be no more SKREEMS.
My suggestions, in order to protect the SKREEM (and in general, the rest of the electronics of the car) are the following ideas that are my general rules for any vehicle manufactured after about 1995:

1) Keep battery cable connections TIGHT and CLEAN. Replace the battery at 48 month intervals; do not buy cheap off brand batteries.

2) Do either one of these $20 mods TODAY:

3) Convertibles: Do not put the top up or down without the engine running.

4) Do not jump start a Crossfire with another vehicle, use a 'booster battery' only. (And of course, do not use a Crossfire to jump start another vehicle.)

5) Do not connect battery tenders or chargers with the car's battery cables attached. Disconnect the car's battery cables so as to completely isolate the car's electrical system from what ever 'tender' or charger you are using.
