Assessing the mileage of the car according to its windscreen?

How can you assess the mileage of the car by examining the windscreen? Here are a few tips:
- When the mileage is bigger than 100 000 km, the windscreen becomes matte. The firsts signs of wear become visible.
- When the mileage is bigger than 200 000 km, the windshield can have circular scrapings.
- The frequent use of wipers can cause scrapings on the windshield due to the wipers being worn and due to the sand getting under the wipers.

For me personally, the mileage is not important. The car is supposed to be driven. It's only important whether it's in a good shape and whether somebody has been taking care of it. However, when you find out that the seller is hiding the real mileage of the car, you know he's not trustworthy.

Timing belt replacement - Subaru GL 2.0 '97

First of all, I've bought a new car which is Subaru mentioned in the title. Mazda 626 is not a very interesting car in the long run.
I didn't know when the timing belt was replaced, so I had to do this first thing after I bought this car.

I was a bit stressed since it was the first time I was doing this operation on my own and we all know how important timing belt is. I took my time and did everything very precisely.

First I drained the coolant and removed the radiator with fans.
Then I removed the two drive belts.

Removing the crankshaft bolt and pulley was a little bit tricky. Many people remove the bolt, using the starter. I didn't want to try that. I simply put the car into 5th gear and applied the brake, and I was able to remove the bolt.
The crankshaft pulley itself was more stubborn. Probably due to rust it didn't want to come off easily. I had to use a lot of penetrant, hit on it with a rubber mallet and pry it with two wrenches at the same time.

Then I just removed the covers and had access to the timing belt.

I removed all the pulleys, the tensioner and the water pump with the thermostat. I replaced everything. Here is how it looked like after the job was done:

I put everything back in place, filled the cooling system with coolant and started the car. Everything worked perfectly. I'm very proud of myself!
