Hey there Londonderry is pretty good!! Went there a couple of weeks ago with all mods on signature and even told them how to start with PMT still in there and they did warranty work. They did rear pinion seal i believe and the recall for the dash pad !! Even did tranny service and changed out the stock pan to BD tranny pan and put oil I anted in there after I supplied it !! service girl was top notch kept me informed and kept the coffee perked!!
