The 4/4 was called 'Woodstock' as it's very yellow and so is the bird in Peanuts.
The three wheeler is called 'The Elk' as it's mission in life is to get cars to fail the Elk Test (in the news when I bought it as the first A class Mercedes failed, and it prompted a redesign).
Neither was named by me, my mum came up with Woodstock, and somebody who worked for Radio 1, The Elk.
