A classic car is one where:

• the age of the car at the end of the year of assessment is 15 years or more and
• the market value of the car for the year is £15,000

I found a 1968 Jaguar MkII for sale for £15,000 on

The Mark 2 gained a reputation as a capable car among criminals and law enforcement alike; the 3.8 Litre model being particularly fast with its 220 bhp (164 kW) engine driving the car from 0-60 mph (97 km/h) in 8.5 seconds and to a top speed of 125 mph (201 km/h) with enough room for five adults. Popular as getaway cars, they were also employed by the Police to patrol British motorways.

The Mark 2 is also well known as the car driven by fictional TV detective Inspector Morse played by John Thaw

Assuming the list price was £2,000 (I can’t find the actual list price), the taxable benefit in kind would be £2,000 x 35% (maximum)x 40% (higher rate tax) = £280

As long as the Market Value is below £15,000 these rules apply above £15,000 the market value is used for the calculation, you can pay for your private fuel to avoid the tax on that.
