Buying a used car can vary in terms of the simplicity and speed of the process. You might find the perfect vehicle online only to realise it has issues when you come to see it in person. This is why a vehicle history check can be an important element of the buying process.
All in all, you can expect a process of at least a couple of hours. This will include getting as much information as you can from the seller, a test drive to check how the car drives, and the process of exchanging money. One of the benefits of buying used over new is the ability to drive away the same day.
