Hi.

I have two questions concerning the use of prepositions.

First, Can we use the preposition to for reach or not?

Ex. The amount reaches to 10kg.

Second, is it possible to use with as a preposition for similar instead of to?

Ex. your car is similar with mine.

Thanks for your time and help in advance

Yes, but not as in your example.
It is rather rare, and is used in a context of imagination or visualization.

Reach can be followed by an infinitive.

The tall buildings seem to reach to the sky.
The space program lets us reach to the stars.

The plague might reach to the boundaries of the empire.
The light did not reach to the dark corners of the hall.

She reached to pick up the newspaper across the table. (with an infinitive)

No.
You will see similar with respect to; similar with regards to in statistical studies explaining the similar characteristics of two groups. e.g.

The two study groups were similar with regards to age and gender.

You wouldn't use to. You would just say the amount reaches 10 kg. But I also wouldn't use the word amount with 10 kg, I would use the word weight. The weight reached/reaches 10 kg.

We don't replace 'to' with the word 'with'.
