Hi. I'm reaching out to any G owners in Korea?

I'm about to dive into Lambo ownership and just needed some info on maintanence cost at the Lambo dealer or other specialist shops here?

The car is a Black Dec/2006 with 16,800km - Hamann kit. EGear.

I'm used to fairly high costs for servicing as I've just sold a 997 GT3 RS. But I understand that A Lambo is going to cost me a lot more. I'm just not sure how much?

If anyone in Seoul can give me a clue as to how much for the below items based on personal experience, either at the official dealer or other specialist repair shops in Seoul. Are there any? Or is my only option the official dealer?

Annual Service cost?
New Clutch?
Brake Pads?
Oil change?

Any help would be much appreciated as this is a big move away from the predictable 911 for me.

Regards

Kevin
