Pick up a nice little runner at the car auctions, tax it, insure it and fill it up with enough petrol to get you from London to Newcastle and back and you'll still have enough change left out of £200 to buy a Magic Tree air freshener.
Attempt to buy two peak time train tickets for the same 635-mile journey and you could be forking out £314, according to Auto Express magazine.
Though trundling up the motorway for five hours in a second-hand Sierra is arguably less salubrious than letting the train take the strain for a mere three hours and 20 minutes (delays, cancellations and leaves on the line permitting), the £114 saving may tempt some.
Taken to its logical (or perhaps illogical) conclusion, the car versus train argument can be extended to compare the prices of a whole range of vehicles.
Tube v Rocket
London's underground railway network is not one of the cheapest subway systems in the world.
A ticket for travel in the city centre, between Covent Garden and Leicester Square on the Piccadilly Line, will set you back £1.50.
Since the stops are a mere 300 metres apart, that equates to £8.04 per mile.
Space travel has proved to be one of the more expensive human endeavours.
When space tourist Dennis Tito blasted off for the International Space Station, he had had to shell out a massive £14m for the pleasure.
However, given that the 60-year-old financier travelled around the world hundreds of times during his six-day holiday, he was paying a bargain £5.61 per mile.
Mersey Ferry v QE II
In Liverpool and need to get across to Birkenhead? The Mersey Ferry (as well as being an inspiration for a Gerry and the Pacemakers song) is just the ticket.
The trip across the river from the Liver Building to Seacombe is just a shade more than 1km with a single fare set at £1.00. That's £1.76 per mile.
The day of the great ocean liners might be over thanks to cheap air travel, but many still yearn for games of shovelboard on the deck and dinner at the captain's table.
An "inside" cabin on Cunard's Queen Elizabeth II costs as little as £1,463 for a voyage from Southampton to New York. That means the transatlantic trip comes in at a little over 42p per mile.
Getting to and from the airport can often be the most arduous part of your journey. The Heathrow Express, with its designer carriages, is supposed to make the trip to the terminal less trying.
The 15-minute ride will set you back £12, but since Paddington station is only a little more than 15km from the airport terminals, you pay £1.28 per mile.
Since the Heathrow Express is one of the UK's most expensive train services, it is only fitting it should be compared with one of the most costly airliners - the supersonic Concorde.
Before the Concorde fleet was grounded last year, a one-way ticket from London to New York cost a trifle less than £3,500. Though a price tag to leave many holidaymakers speechless, the faster-than-sound trip still comes in at less than £1 per mile.
