1st question: The state I live in has no McLaren dealerships, where can I take it to get maintained with someone who is certified? I asked the Ferrari dealership and they said they only service Ferrari‘s. 2nd question: During winter when a person who owns a Ferrari or a high end super car and doesn‘t want to drive it in the snow or winter and they leave It sitting in the garage, should they start it weekly for a few minutes? And should they lift the car 6 inches off the ground so the cars suspension doesn‘t wear or does it really matter? And the car would only be sitting for a few months
First question: You don't own one, so there's no need to worry about it. Second question: You don't own one, and likely never will, so there's no need to worry about it.
On a McLaren F1 documentary, the mechanic comes to you. I don't know the answer to your second question.
Pick up phone. Call McLaren dealer closest to you and tell him too send the service team over to your house on a time agreeable to you both. I've never bothered with lifting my cars off the ground,and they sit 9months out of the year. Nor have I someone starting them either. If you have a problem with your Ferrari see answer one
