I assume the steps to be taken in order to buy a car is what you're looking for ?
1,Licence
2,Loan... Know your buying power
3,Select Vehicle,check history
4,Insurance... check for rates being affordable before even considering a test drive
5,Test drive= take to mechanic
6,Negotiate
Are you going to apply for a loan through a dealer, or your own source ?
What monthly payments are you looking for ?
Are you investing a downpayment or financing full amount?
How is your credit ?,,, this being your first car makes me ask if you have established credit to get a loan at a fair rate ?
