For 1k euros you'll get an absolute shitbox that will need 1k euros a year in maintenance, will kill you if you get in any kind of accident and won't be able to drive in most cities because of pollution requirements.

I had to replace the shitbox I bought for 5k euros 10 years ago, the same model/year with twice the kms now costs 9k+. And I consider that the bare minimum in term of road worthiness and safety, cars have been a luxury for a long time
