Make sure you attend this meet, Zach will be there as well as a ton of people who can help you with advice on what you have to deal with.
I'll be there (I think) but point is, it's a great social event but it's also a great place for a new owner - not only can we TELL you about the car, we can SHOW YOU; saves a lot of time when you start working on it.

TODAY, order a spare Crank Sensor and Relay Control Module, put them IN THE TRUNK so you are ready when the car stalls in traffic or refuses to start as you leave the store - it's gonna happen. With those parts, you need no mechanic.... without those parts, no mechanic can help you.
Be sure to visit your local Chrysler dealer any time anything goes wrong so they can take your money and not fix anything. Then go to the Mercedes dealer and hear them tell you it's not their car (it is). IOW, we are all you have for tech support, and it's why so many of us never leave here. I"m on my third Roadster since 2009.

WHen your RCM fails (it will fail, period) put the spare in and send the bad one to DJ in Arizona, for $65 it will come back to you with reflowed solder and four new relays.
