Ford Focus from the Ford dealership

Hello everybody, I’m about to buy a Ford Focus built in 2007. It’s in a Ford car dealership, has run 73000 km and costs 59000€. I’d get a new timing belt plus water pump, new Tüv, a used car warranty of 12 months, a set of winter tires on aluminum, an inspection and a full tank. I’m always very suspicious about buying a car, as I was well pulled over the table when I first bought a car from private. ge: On the brake discs I have seen rust. After the test drive the discs were freed from it. If the dealer says that the Tüv is made new, the brakes would have to be changed if they are not in order, right? Thank you in advance.
