One of British motorsport's traditional celebrations takes place this weekend at the Goodwood Festival of Speed.
As ever, there is a packed line-up at auction, hosted by Bonhams, with a number of former F1 machinery on show.
But which former competitors could be yours [if money was no object]? Take a look below!
Lotus Mugen-Honda - 1993/94
The Lotus Mugen-Honda from 1993-1994 driven by Johnny Herbert and Pedro Lamy is up for sale with an estimated value of £70,000-£100,000.
The car is the Type 107C, chassis 01, and is offered as a display car. It has been rebuilt from the surviving monocoque involved in the horrific Silverstone testing crash that saw Lamy break both legs.
It has been totally rebuilt since, first being put on public display in 2012 at Brands Hatch.
Force India-Mercedes - 2009
The most contemporary F1 car up for auction comes straight from Aston Martin's heritage display.
The 2009 VJM02 was driven by Giancarlo Fisichella and Vitantonio Liuzzi - the former taking a stunning second at the Belgian Grand Prix.
Fisichella was overhauled by Ferrari's Kimi Raikkonen at Spa-Francorchamps having taken an unlikely pole position - one of the biggest shocks in modern F1.
The value estimate for the auction is £60,000-£90,000.
Tyrrell-Renault - 1985/1986
This Tyrrell-Renault 014 is estimated the cheapest of the four 'F1' lots at £50,000-£80,000 and it is only a rolling chassis minus the engine, but exclusivity is a plus point.
Only four chassis were made and it was the team's first 'turbocharge' design.
But the car, driven by Martin Brundle, Stefan Bellof and Philippe Streif was largely uncompetitive and failed to challenge for success.
Lotus-Cosworth - 2013
Ok, this isn't technically an F1 car - but it'll do.
The Lotus Type 125 Monoposto is one of five built for what was supposed to be a racing league for wealthy gentlemen drivers.
Based on the Lotus F1 cars at the time, Cosworth modified its IndyCar engine for the chassis to help create this track day monster. The creation was featured in a segment on BBC's Top Gear, where Jeremy Clarkson was schooled by former Grand Prix winner Jean Alesi.
This example has spent most of its life on display in the United States but arrives ready to drive.
The price estimate is between £275,000 and £350,000.
