Selling to an online car buyer

Best for: speed, no hassle, fair price on desirable cars.

Online car buyers like SellCarInstant, WeBuyAnyCar, Motorway and Carwow handle the whole process. You enter your reg, get a quote, and they collect the car or you drop it off. Money is in your account the same day or within a few working days.

Pros:

  • Fastest route, often same day
  • No strangers at your door
  • Paperwork handled for you, including DVLA notification
  • Most will buy cars on finance and settle the lender directly

Cons:

  • Some charge admin fees deducted from your payout
  • Some are known for reducing the figure on collection day after the inspection
  • Many do not buy cars without a valid MOT

How SellCarInstant is different:

  • The price is locked when you upload photos. We will not reduce the figure for anything you have already declared and photographed.
  • We value from retail price down rather than trade price up. On cars in demand, that means a higher figure.
  • No admin fees. The figure on screen is the figure that lands in your account.
  • £100 extra if you bring the car to Victoria Retail Park, Bury (BL8 2EQ).

Selling privately

Best for: maximum money, if you have the time.

Private sale through Autotrader, Facebook Marketplace, Gumtree or eBay typically gets you the highest figure. The trade off is the time and risk: writing the listing, fielding messages, dealing with no shows, hosting strangers at your home, accompanying test drives, and managing the payment yourself.

Pros:

  • Usually the highest price
  • You set the price and you control the timeline

Cons:

  • Time consuming, often two to four weeks
  • Risk of fraud, especially around payment
  • Cannot sell privately if there is finance on the car (illegal in the UK)
  • You handle the paperwork and the DVLA notification yourself

Part exchange at a dealership

Best for: people buying their next car at the same time.

Part exchange means the dealer takes your old car as part of the deal on your new one. It is convenient. It is rarely the route that gets you the most money, because the figure is wrapped into a wider transaction and the dealer needs to make a margin on it.

Pros:

  • Convenient if you are buying a car
  • All paperwork handled
  • Most dealers settle outstanding finance for you

Cons:

  • Lower figures than online buyers or private sale
  • You are tied to the dealer's stock for your next car

Selling at auction

Best for: classic, specialist or unusual cars.

Auctions are good for cars that need a specialist audience: classics, collectibles, modified cars, or anything where a normal buyer would underprice. For an everyday family car, an auction is rarely the right move.

Pros:

  • Fixed sale date
  • Reaches a specialist audience

Cons:

  • Auction fees deducted from your sale
  • Slow on payment, often two to four weeks
  • No guaranteed sale, the car can come back if it does not hit reserve

Selling for scrap

Best for: cars at the end of their life.

If your car has failed its MOT, has serious mechanical damage, or is older than its repair value, scrap is sometimes the only honest option. SellCarInstant does not buy scrap cars. For scrap, use a comparison site that pulls quotes from registered Authorised Treatment Facilities.

How to choose

In short:

  • If speed matters most, go to an online car buyer
  • If money matters most and you have a clean, popular car, sell privately
  • If you are buying your next car at the same time, part exchange
  • If your car is unusual, classic or specialist, try auction
  • If your car is at the end of its life, scrap

Most cars in the UK now sell through online car buyers because the trade off (a small amount less than private sale, in exchange for a same day cash sale and no hassle) is what most sellers actually want.

Frequently asked questions

What is the quickest way to sell a car?

An online car buyer. SellCarInstant can complete the sale and pay you the same day if you bring the car to us in Bury.

What gets the most money for my car?

Selling privately almost always gets the highest figure, with the trade off of time and effort.

Can I sell a car with outstanding finance?

Yes, through an online car buyer or dealer who will settle the finance with the lender. You cannot sell a financed car privately in the UK.

Do online car buyers reduce the figure on collection day?

Some do, especially if the inspection finds something not declared at the quote stage. SellCarInstant does not reduce the figure for anything you have already declared and photographed.

Is it worth selling my car privately to make more money?

It depends on the car and the time you have. A clean, low mileage car in popular spec usually justifies the extra effort of a private sale. A higher mileage or older car often gets a similar figure from an online buyer once you account for the listing fees, the time, and the risk of no shows.
