My car broke down under me

Hello everyone!

Me and my wife recently moved out from our parents to live with eachother,so we are in a rented apartment. We are pretty much earning 760€/month, as you can tell in Hungary that is pretty much a shit earning/month.
The main reason is that im here is pretty much this:
This car is an inherited car from my granddad, he loved this vehicle, but he havent had any time to told me whats wrong with this car.
This is a 2000 BMW E46 318i

a few days ago, i went to work at 7:00 am , but my cars interior cooling system , and my servo control engine just died whilist im driving, so the cooling fluid , and the servo oil just drooled down on the roads, i have 2 leaks in the cars system now , and i crashed my car because of the servo system.And this is our goto car, go to work, go anywhere.... without our car we are pretty much fucked.....im sorry for the foul language, but thats what im thinking atm.
We will pretty much need to replace the cooling system, the cooling enginge, and the cooler the car mechanic told us that will be near 450€s,
then we have to replace the servo-motor and the servo-oil the mechanic told us that will cost like : 350€
And there is one last problem and that is the cars left side, we have to change the left wing fender, the hood, and the front bumper that is pretty much 200€s, and we are still yet to repaint those to match the car colors that is the only thing that can wait...

The main reason is that im asking for help here, is because, we are paying the rent which is 360€, the bills are pretty much 250€ and we left with 150€s to live in the rest of the month, that is pretty much 3 weeks/month. So at this stage we cannot afford to repair our car, thats why im looking for some kind of help , we asked our parents first, but they cant help us because winter just started. by the way we live in a city that is 50km away from our workplace, and we cannot afford to go with a bus for the rest of the month, and there is absolutely 0 train traffic where we live, if we want to go with a train we have to go 15kms to just go with a train... and the 2nd reason is , i got this car as my granddads last gift, after he passed away and i would like to repair it at any costs because of him.
So i dont know how will i thank you for your help , but i want to thank you in some ways. If you are that person who wants to help us to maintain our jobs, if you are that person who wants to help us repair our car, i would sincerely accept anything.
I've never had anything like this before this is my first time problem with this car.

With many thanks:
Norbert Nagy and my wife Szilvia Nagy
