When I was travelling in Vancouver a few months ago.,

This is a sentence fragment

Mmy friend drove me around using his Tesla Model 3; he complained that the insurance fee for Tesla was profoundly high, which was nearly CAD$ 500 a month after thea discount., was profoundly high

Although he has been working inat an insurance company for a few years, he cannot afford thehis living expenses perfecteasily.

He said the salary for most people who were living in the city was under $3000 a month, and maintaining a comfortable life was quite a challenge.

Normally salaries are given as a yearly salary, so it may be better to specify here.

The yYoung generations prefer EVs, even though the insurance fee is much higher than that of traditional gasoline vehicles.

However, he didn't want to see the litres and dollars scrolling up on the pump at the gas stations, so he bought a Tesla.

"However" makes it sound like this is in contrast to the previous sentence.

To be honest, I even cannot afford a Tesla, so his financial condition is better than mine.

When I was travelling in Vancouver a few months ago, I rode with my friend in his Tesla Model 3.

If this post was about seeing Vancouver, and your friend drove you around the city, I think "drove me" would be the better verb to use. Since this is mostly about the Tesla Model 3, I think it sounds better to my ear that you rode around in the Tesla.

My friend drove me using his Tesla Model 3; hHe complained that the insurance fee for Tesla was profoundly high, which was nearly CAD$ $500 a month after the discount.

I moved part of this sentence to the first sentence, which then sounded more complete.

(I don't drive very much, and this seems like such a high insurance premium!)

Although he has been working in an insurance company for a few years, he cannot afford theall his living expenses perfectly.

Another phrasing to use here would be "he cannot afford his basic living expenses" but that gives the impression he might not be able to afford rent and food when he seems to be doing okay enough to pay for a Tesla and his insurance premium.

He said the salary for most people who were living in the city was under $3000, and maintaining a comfortable life was quite a challenge.

Is this $3,000/month?

TFurther, the young generations prefer EVs, even though the insurance fee is much higher than that of traditional gasoline vehicles.

However, hemy friend didn't want to see the litres and dollars scrolling up on the pump at the gas stations, so he bought a Tesla.

To be honest, I even cannot even afford a Tesla, so his financial condition is still better than mine.
