Dante Credaro, president of TeamLamborghini (see
http://www.teamlamborghini.com) has put together a firm where they can help you with any questions and/or repair on your Lambo. Their mechanics will also come over to your place in the US from Italy and work on your car (and fix it RIGHT the first time). They worked on mine and did a great job.
Prices are reasonable (actually most likely cheaper than taking your car God knows where, for God knows who to work on it...). By the time I paid for the mechanic to come over and work on my car, it was cheaper than sending it to the closest dealer (Atlanta), paying for the round trip shipping, plus being without the car for who know how long...
