Where is the best place to sell a Porsche in the UK?
Every way to sell a Porsche in the UK, what each one costs and who it suits.
Prices checked on each company's own website on .
The short answer
It depends on what matters most to you: the price, the effort or the speed.
- For the highest price, sell privately. The buyer pays a retail price and no dealer's margin comes out of it, but you answer buyers, show the car and take the payment yourself. As Honest John says, you generally get the best price by selling privately.
- For help, at a cost: an online auction or sale or return. An auction sells the car to the highest bidder within a couple of weeks; a specialist's sale or return deals with the buyers and viewings for you.
- For the least effort: part-exchange or an instant buyer. A dealer or an instant buyer can take the car within days, at a trade price.

The best websites to sell a Porsche privately
A private sale usually brings the most money, because the buyer pays a retail price. In return you write the advert, answer buyers, show the car and take the payment. Where to advertise depends on who you want to reach: general car sites put your Porsche among cars of every make; Porsche-only sites and the clubs put it in front of people who already know what a 997 GTS or a Paint to Sample car is worth. Many sellers advertise in more than one place.
Sonderwatch
Sonderwatch is a UK search for used Porsches from Porsche Centres, specialist dealers and private sellers, with 7,875 for sale today. Buyers search it the way enthusiasts think: by generation, exact paint and interior, and factory options such as PDCC, Sport Chrono or ceramic brakes. Your advert sits in the same search as the dealers' cars, buyers whose saved alerts match your car hear about it by email, and buyers message you through the site, so your email address stays off your advert. Free for adverts published by 30 December 2026, until the car sells. From 31 December 2026: £14.99 for 2 weeks, £23.99 for 4 weeks or £49.99 until sold. No commission. Sonderwatch advertises your car: the sale and the payment are between you and the buyer.
Auto Trader
The general car site. For a car worth over £24,999, an advert costs £48.95 for 2 weeks, £59.95 for 3 weeks, £78.95 for 6 weeks or £99.95 until it sells, with up to 100 photos.

PistonHeads
The motoring enthusiasts' site, for every make. A classified advert costs £34.99 for 30 days (£44.99 for a few supercar makes), and members of 10 years or more advertise free. It also runs auctions (below).

Car & Classic

Selling a Porsche at auction
An online auction puts your car in front of bidders for about a week and sells it to the highest bidder. It suits cars that draw a crowd: rare specifications, low mileages, collectable models. At Collecting Cars you receive the whole winning bid: the buyer pays a premium of 7.2% including VAT, at least £1,200 and at most £7,200, once the bidding meets your reserve. Car & Classic charges the seller 6% + VAT, at least £600 + VAT, and only if the car sells. PistonHeads auctions, for performance and classic cars worth over £5,000, are free to list, and the buyer pays a premium instead: a week's preview, then a 7-day auction.

Sale or return with a Porsche specialist
A specialist sells your car for you from its showroom: it agrees a retail price with you and deals with the enquiries, viewings, negotiation and payment. RPM Technik, a Porsche specialist, says the cars it sells spend 31 days in stock on average. Before you agree, ask what the specialist keeps, who insures the car while it has it, and when you are paid.

Part-exchange, or selling to a Porsche Centre
The simplest way: the dealer takes your car when you buy your next one, or buys it outright. There is no fee, but the offer is a trade price, based on what the car is worth to the trade, because the dealer's margin comes out of it.

The quickest way: instant car buyers
Motorway puts your car in a daily online auction for dealers, and the winning dealer collects it from your home. There is no upfront cost, and a service fee of £29.99 to £119.99 once it sells. webuyanycar values your car online and buys it at one of its branches after an inspection, for a transaction fee of £124.99 on a car of £20,000 or more; the money reaches your bank within 4 working days, or sooner for an extra fee. Either way your car goes to the trade, at a trade price.

Questions sellers ask
- What is the best website to sell a Porsche?
- It depends on the buyers you want to reach. General car sites such as Auto Trader put your car among cars of every make. To reach people who know Porsches, advertise where they search: on Sonderwatch, where enthusiasts search by generation, paint and factory options; on PistonHeads; or in the Porsche Club GB classifieds if you are a member. Many sellers advertise in more than one place.
- Is it better to sell a Porsche privately or to a dealer?
- Privately, if the price matters most and you can deal with buyers and viewings yourself: a dealer pays a trade price, so that it can sell the car on at a profit. A dealer, if a quick and simple sale matters more.

- From nothing to a few hundred pounds. An advert on Sonderwatch is free if published by 30 December 2026, and on Car & Classic it is free; on Auto Trader, £48.95 to £99.95 for a car worth over £24,999.

Prices checked on 9 November 2026.

- No. Sonderwatch advertises cars: it takes no part in the sale and holds no money. On Sonderwatch, buyers message you through the site, and the sale and the payment are between you and the buyer.
