Another update: (keeping the thread alive!)
I have dropped my car this morning and I must admit that Fort Lauderdale service is awesome!! Lamont, the MINI advisor, really rocks!!!

He does care about MINI and he knows his stuff. I've had a problem with my xenon leveling system for a long time now and he found the problem... defect headlights... so he ordered a new set and I will have my car by tomorrow afternoon. This guy, and his technicians, are really great!
The dealer even loaned me a car for the whole day...A clean Dodge Magnum!
Way to go Fort Lauderdale!
And, Vista MINI is really disappointing... They are in for money... Fort Lauderdale charged me 40.00$ less than Vista for the same job...
I wrote to MINIUSA about Vista and I got a reply telling me that they were sorry about that and that Vista was independant so there was nothing they could do... Maybe giving MINI a bad reputation isn't enough for them...
