used model Y 2021 (preupdate) coming from 17 model 3

I was the owner of one of the first 5000 batches of 2017 Model 3 long range RWD (got it used from Tesla in 2018 with 6k miles)

Sold the car because CarMax wanted a ridiculous amount of money during the peak of used cars, especially EV, and got a beater 1992 Nissan until the car market cooled down.

Now that the car market is looking solid again, I decided to purchase the 2021 Model Y standard range RWD with 36k miles for 26.5k from Tesla (white interior, blue exterior).

​

Anyway long story short, I know the Model 3 and Model Y are different but besides the sizes are there any other differences in the car? I remember Model 3 being very noisy, had to get it serviced 5 times.
