What about the dreaded "required service" that supposedly has to be done by an authorized dealer to keep the warranty in effect? (The warranty on your car is obviously gone now, but, "back when"?)
IIRC the warranty on the car was 2 years only so in that 2 year span i only got the car serviced once at the dealer to make sure everything was all right and for them to perform all the required "campaigns" on the car. i believe i paid $1600.
the car has been here in the philippines for almost 8 years and we have no lambo dealership over here so the car has been serviced by my trusted independent shop and i never had any problems with the car neither did the workshop have any issues working on it. in fact, they even converted the car to RWD easily. further, there is already a great wealth of knowledge on how to work on lambos that can be found on the forums so everything is quite easy.
all i can say is the car has been bullet proof for me. and i've been very happy with it. the only major service upcoming is valve adjustment at 15K miles. i have a service manual on a CD so will just get the specs from there and bring it to the workshop again when the time comes.
