The easiest way to buy a car is to go to the dealership, pick out the car you want, and pay sticker price, financing the purchase with a car note from the dealership. The easiest way is also the costliest way.
For the longest time my daily driver was a 2002 Dodge Durango. I bought it for $4,000 in 2010. It wasn’t a great car and got lousy mileage. I don’t recommend you get one.
I think many people stay in the poorhouse due to what they drive. I’m always appalled to hear about someone making $30,000 to 40,000 a year who has an $18,000 car loan. Bizarre to me.
