Private sale can make you earn a net exchange of more than 20 percent

If you need to whip your current wheel, you have two options. You can partially replace the car at the dealership, and the dealer will give you a price and then deduct it from the total cost of the car you purchased. Or you can sell it privately - there you list the car and get cash from the person who bought the car.

Parts exchange. This can save a lot of trouble, but it is difficult to save money. Yes, it prevents you from having to advertise or deal with potential buyers, but it's a big problem, but you won't get as much benefit as private sales. Remember, the price paid by the dealer will be lower than the value of your car, so it can move forward in a profitable way. So weigh the quotes carefully.

Sold privately. This is time consuming, but if you are willing to work hard, you are likely to get more money. Options include Gumtree (free), Pistonheads (30-day advertising fee of $11.99), Autotrader (free shipping for cars under $1,000 for free, $36.95 for cars over $1,000) and Motors (12-week free advertising) fee). Other options include selling cars on eBay or Facebook.

We investigated the number of cars you sold privately and searched for the value of several models on professional and found that the price difference for private sale is typically 20% higher than for parts exchange.

If you really decide to make a partial exchange, then be aware that the dealer is pushing up the discount on your old car – making it look like you got a good deal – but at the same time charging for the new model More fees. Just check how much cash you will pay after changing the car. This is the real cost of the transaction.

“How much do I have to spend?” Checklist

Before you start calculating, you need to decide what kind of car you want.

You can view each model online. What car? Kabuye, Honest John and Parks are among the best sites for research purposes, and don't forget the top sites with a lot of online reviews.

You need to budget for two types of costs: upfront costs and ongoing costs. Check that you have considered all of the following and budgeted for it:

Any upfront costs. Once you decide to buy a car, you of course have to pay for it. You can pay the full amount in advance or make a financial transaction. No matter which method you choose, you must pay at least one advance payment before driving.

Financing repayment. If you accept personal loan or dealer financing, you need to consider repaying - read more about your financing options.

Fuel. To calculate the approximate cost of a new car, there is a fuel consumption search tool on the internet. The car website honest John also has a handy "real mpg" section where the driver has reported how many miles per gallon they actually get. For information on how to reduce costs, please see our Guide to Cheap Gasoline.

Tax. You can check how much road tax you need to pay on internet. You can also search for cars within a specific tax range (A-M depends on the car's CO2 emissions). The tax cost for the first year ranges from $0 to $1,000. Standard rates apply up to a maximum of $500/year.

Car insurance. The cost of insurance depends on the insurance company's perception of you. If you are a young person who has just passed the exam, you will pay more for insurance. In addition, insured failure insurance will increase costs. New cars usually have one year of fail-safe. For tips on how to reduce costs, please see our Guide to Cheap Car Insurance and Fail-Safe.

MOTs. Once the car is three years old, you have to pay the fare for one car a year, and the fare is $54.85 (for testing). Save money by using our MOT guide, including taking exams at the local council center, which saves you $100.

Service. You need to maintain your car on a regular basis, usually once a year, but it varies by model. Maintenance ensures safe driving and the manufacturer's warranty is valid. Routine services usually start at around $120.

Parking permits and tolls. You may be required to pay a resident permit unless you have a free parking lot or garage. Check out your committee website to see how much it costs. If you are also driving, consider any costs of parking at work and the tolls you may face along the way.

Other expenses. New tires, repairs and valet cleaning can add up, so make sure there is some breathing space in your budget. So an extra $100 is allowed each year, just in case.
