1., 2. and 4. must be paid every month.
i'm assuming you don't have GF, otherwise your 2. wouldn't be that low.
so in reality you only have 1k for your intention of paying car monthly installment, petrol and maintenance + savings.

if monthly repayment is 600, petrol is 300, you only left 100 for maintenance? what happen when your car need major service? annual roadtax + insurance? do you want to be GF-less for this whole time? no saving for this whole time?

you can choose above option and stay like that for 2-3 years and pray that your job is secure for that whole time until your increment is enough to ease the burden. or you can save the 1k for 1-2 years and use it for deposit and that time hopefully your increment is enough to pay for the installment.

Now realise I overlook your 1st post that you got mention you have GF. So the more reason you need to save money, for marriage.

There is another choice, to get cheaper car such as Viva or 2nd hand car. Buying cash for the 2nd hand if you can afford. But of course you need to be very knowledgeable about your car so you can minimize the maintenance cost.

But in the end you'll feel that using bike is still the most friendly to your wallet.

confirm gigolo!

i use 17 years old car also can get chick.
