You have the service maintenance plan in your cars booklet.
Basically an oil change every year or every 15'000km. So for you it's only an oil change and inspection of everything like described in the plan.
It's about half the cost as it was on the Gallardo. The oil change is easier but the engine still has several draining points and panels have to be removed to gain access to them. Here in Europe a lambo dealer charges about $1000 for this work and fluids (I've got a Bentley Continental GT as rental car what was included).
