I am thinking of buying a 2007 Lexus LS 600h. Being a high end car, with all the electrical equipment, I am worried that something might go wrong with it. I'm realistic enough to be ready to spend some money on maintenance (for the size and age of the car). Prior to buying, what do you think I should check out? Is it acceptable to ask the seller if I could take the car to a Lexus dealer to have it checked or is that something unheard of? I don't want to ask in case of sounding like a complete idiot. Not many garages will let you take their cars to be thoroughly inspected. Does AA Ireland provide a vehicle check service where its technicians come out to check your car for a fee?

Thanks for any information at all.
