Help restoring my car

Hello,
My name is David. I'm a student from Slovakia. I would like to ask for your help to restore my car to its best form. In our country it is very hard to earn enough money to maintain a car, still i feel lucky enough that I was able to buy one. It is similar to one of my dream cars a BMW e46 M3. Sadly, it is old and the previous owner did not take care of it at all. A lot of money was already spent on it, but there is still more to do. Your help would be the best thing that can happen to me right now. I have changed the front suspension, all four brakes, tires but there are still problems with the electronics and I can't fix it by myself. Also its consumption is higher than usual, so the engine needs a check up as well. I think that this car is a real beauty and it deserves the care that I would like to give.
