TEG as my Roadster is an example of easlry adopters, it was the first CPO in the state of Texas, and probably one of the first to be fully repaired by a third party. The PEM failed completely and was quoted $9800-$11,000 to repair by local SC. So the Forum coming to my rescue recommended Gruber Electronics in Phoenix. So off it went. Six weeks in and and estimate of $5-7K I believe Im still better off than waiting at SC. As a side note I had about an 8 week SC ordeal last summer when the headlight needed repair. so it does seem the knowledge is filtering down.
