Is spending $12,000 on a used car too much for a used car? (First Time Buyer)?

I've been looking at mostly Ford Fiestas and recently Volkswagen e-Golf cars… There isn't really that much of a price difference with the low-ish mileage. I would be spending about $12,000 for a car with 25,000 miles on it for either car (in my area). I've always wanted a Volkswagen… Should I go with the Volkswagen? And I need a car with a hatchback since I'm going to be moving soon for college. Anyway, I've tried finding cars in under $7k but there just wasn't many options with a lower mileage… That were decent cars anyway. Would a Volkswagen be a good first car? And is a $12,000 a better budget than $7k? I can make it work either way… But since it's my first car I'm not sure which I would get better bang for my buck. If you know what I mean. Thanks in advance!

I would also be commuting a lot for work and school… Fyi. Thanks again in advance!

Which car should I buy for my first car?

I'm thinking of getting a used version. But these are the cars I'm thinking of testing out:

1) Fiat 2) Nissan Leaf SL 3) Ford Fiesta

I don't want to go over $9,000 for a used car. And the Nissan Leaf would probably be my best option even though I really want a Fiat, but I can't find one yet in my price range. And I need a car pretty soon before January… Anyway. Would buying a used car that has 19,000 miles on it for $7,000 be a good deal? This would be for a Nissan Leaf. A used Ford Fiest would cost me at least $14k (USED)… Which is what I'm kind of nervous about. I've never bought a car before… But it only has 9,000 miles on it.

Are Nissans good cars? I've only ever had experience with Ford's because my family has a Ford car. And I do like how they drive etc… Not a Ford Fiesta though (Explorer).

For a first car what should I look into buying more? Thanks in advance.

Added (1). But I really want to try and find a Ford Fiesta under $9k because I don't want a fully electric car yet… Plus I'm going to have to commute pretty far to work too.

Car ride bumpy between 45- 50 mph?

I bought a ford fiesta 2008 Ghia tdci diesel. The car drives fine up until around 45 mph. The ride gets bumpy and shaky. But the steering wheel is not shaking at all. Then after about 55mph the ride smooths out again and is fine as you increase the speed. The bumping is only really happening when I'm accelerating at these speeds. Once I take my foot off the gas pedal it stops. The car had had three new tyres. And the passenger side drivers shaft has been checked and it isn't the problem. Has anyone encountered this?

Should you connect your phone to the radio for your driving test?

I'm about to take my driving test and my car is a 2019 Ford Fiesta SE so it has one of those radios where you can connect your phone for emergency phone calls and stuff. Should I connect it to show that I'm prepared Incase of an emergency, or should I not connect it so that I show I'm not on the phone while driving? It would be especially bad if someone tries to call me in the middle of the test.

Will different tyre tread depths fail the MOTA?

As the title says, will different tread depths on the tyres on my Ford fiesta cause it to fail its MOT? The tread itself are all legal and in good condition the only thing is one tyre has a different tread type to the other 3, will this cause a fail? I have read different things online, some saying that it will be fine as long as the tread is in good condition but other sources saying its illegal, can anyone clear this up please.
