Gran Turismo 7 Receives Lowest User Score Amid Microtransaction Issues

It is normal for a game to get reviews after its launch, but it is bad when all it gets are bad reviews and scores. The last game to get a bad score from Metacritic is Gran Turismo 7.
Gran Turismo 7 experiences some downtime, and is under fire after the problems the game encountered with its microtransactions. The game received 2.5 out of 10, which puts it under some games such as Cool Boarders 2001 and World of Warriors (for PS4). This is the lowest score that Metacritic has given in its history of tracked games.
Gran Turismo 7 was offline for more than 24 hours, and it has gotten harder to get a car without spending a large amount of money when compared to Gran Turismo Sport. If a player wants to earn credit to buy an expensive car in the game, they have to complete around 20 hours, which is quite a lot. Not to mention the out-of-this-world microtransactions.
As a response to these comments, Kazunori Yamauchi, the series boss, has said that the pricing of cars is a crucial game element that would mark their value and rarity, so for him, the expensive microtransactions are very justified.
What do you think about these microtransactions? Have you bought any car in Gran Turismo 7? What amount of money did you pay?
