Anytime any warranty work will be needed, it's going to take time, so best to have an alternate vehicle around. We opted to get the Maximum Care protection that gives you a rental car for anything that is needed from an oil change to a full engine rebuild, from 7/70K protection... Cost was $1,800, but it may be worth it in the long run since parts are rare, and have to be brought in from Mercedes/Karmann or whether they get them... The E19 fan control module fix and a few other minor things regarding the stuck on protective plastic (on the lot for 390 days in the sun) ruining the rocker panels and needing repainting took nearly a week... We had a rental the whole week at no charge. Sunnyvale Chrysler Plymouth in Calif. has the right techs for the job and they left it sparkling thereafter... But, be prepared for long waits on repairs. You might want to shop around for a DC dealer with a shop that has been trained in the SRT vehicles, and especially the SRT-6. Even if you have to drive a bit out of the way, it sounds like it will be worth it.
