Not sure what to expect, advice?

Bear in mind that rubber age hardens, particularly if it is not kept immersed in oil/fluid.

So watch out for the rubber parts:

- the brake master cylinder. There is a rubber cup on the end of the piston that will harden if not exercised. This results in the brake pedal slowly falling toward the floor as it is held.

- the brake slave cylinders.

- engine, transmission and power steering seals. These tighten up as they harden and then don't seal. They can be loosened up with a good seal conditioner that replenishes the lost elastomers, such as AT-205. Careful, though. Some seal conditioners act to partially dissolve the rubber, and that is not good. Get the good stuff. One bottle in the engine oil. One in the trans. Part of a bottle in the P/S pump.

- Of course you are going to need new windshield wiper blades. Easy to forget until it rains.

- Something to replenish door and window seals. If anybody has a good suggestion here, please pipe up. Again, something that is easy to overlook until it rains.
