There are alternative to overdrafts and those would be loans which you can apply for. You will find the interest rates for automobile purchases are high because of the depreciation of the vehicle as time goes on, a bank loan will be less than an overdraft and easier to manage. Ask in your bank about the loan and they will take your earnings into consideration. But factor in things like repairs and also illness if your off work this all needs to be thought about
That's probably the stupidest idea I've ever heard. You should have literally zero desire to go anywhere near an overdraft.
Save your money. Buy a car when you have money.
I doubt it as you are still a minor in UK law.
No harm in asking though.
lol. SIT ON THE BUS !! It is the better economic option.
