状況に応じて、2通り答えを提案させていただきました。
まず「① Buy a new car」は単純に新車を[買う](https://eikaiwa.dmm.com/uknow/questions/35187/)ことです。[車](https://eikaiwa.dmm.com/uknow/questions/52255/)を買い換えるのニュアンスは入っていませんが、買う事自体が目的なので、これが一番無難かと思います。
そして、もし車が故障して買い換える必要があるならば「② Replace the car」を勧めます。
意味的には、「前の車が使えないので、替えます」です。
パソコンでも同じ様に使えます。状況に応じて、判断し、使っていただければと思います。

It depends really whether you wish to inform people about your decision to buy a new car, or the actual arrival of the new car. Probably the news of the car arriving is a little bit more interesting than your decision!
"Guys, just thought I'd let you know, my new car is being delivered to me here tomorrow."
"That's great - you can take us all for a spin!"
I am getting a new car.
By using the word "getting" you are telling the person you are speaking to that you will have a new car soon.
You do not have it "now" at this moment.
My new car will be delivered soon.
This sentence lets someone know that you have bought a new car, but you have not gotten it yet.
Perhaps it is still at the dealership, you are waiting on paperwork etc.
You own a new car, but youdo not have it in your poseesion yet.
I am getting a new car.
"getting" という言葉を使うことで、もうすぐ買うよ、というニュアンスを足すことができます。
現在はまだ持っていません。.
My new car will be delivered soon.
この文では、相手に新しい車を買ったけど、まだ納車されていないという時に使います。
もしかすると、まだディーラーの手にあって、書類上の手続きなどを待っているのかもしれません。
しかし、まだ所有はしていないんですね。
I am ready to buy...and I am searching for a new car!
Searching for /Looking for something, implies strong interest in " finding " or
securing the" object of desire":
I might just say..." I am looking for a new car right now" and that would be enough
to communicate the message..."I am buying a new car."
Searching for /Looking for は、どちらもあるものに対して、強い興味がありそれが欲しくて探しているということを意味します。
" I am looking for a new car right now"
今、新しい車を探しているの。
というのが、これから車を買うということが相手に伝わるので一番ぴったりくるでしょう。
Buying a new car is exciting news!
If you would like to explain this to friends or family and let them know how excited you are, you can use the sentences above.
"My new car is a day away from arriving!! Let's celebrate."
"I bought a new car, I will collect it this weekend."
If you have decided to buy a car but have not yet made arrangements for it, use the following sentences:
"I decided to buy a new car."
"I am planning on buying a new car."
"I am in the process of buying a new car."
I'm heading out to the dealership to shop for cars.
I'm going to the used car lot.
"showroom" and "dealership" are two words we use here in the US (I don't know about other English-speaking countries) to talk about the place where you can go to look at cars, especially new cars. Normally they are indoors and you have to bargain with a salesman. Some people like bargaining but I don't. A few dealerships have a "no bargaining" rule.
you could say something like
"i need a new car!".
or
"my car is too old, I need to replace it".
or
"this computer is too old, i need to update
it to a newer model".
以下のように言うことが出来ます。
例文
"I need a new car!".
新しい車が必要だ
又は
"my car is too old, I need to replace it".
私の車はあまりに古いので、買い換える必要がある
又は
"this computer is too old, i need to update
it to a newer model".
このコンピューターは古すぎるので、新しいモデルに買い換える必要がある
When you want to explain that you are going to buy a new car, then you can say one of these two sentences.
For example.
What are you doing today?
Well, I am going to buy a new car.
Fancy. Anything in particular?
I hope this helps.
Have a great day.
