Mono Monday : Four Wheels for Four Years!

Happy 4th birthday to Mono Monday!
Having thought I was recovering from the lurgy, I am in full relapse and fed up with it too, so this is the best I can do for a blip today. 
As the theme is Four, I have taken a snap of my four favourite wheels. They aren't going anywhere over the next few days until I bounce back and the weather improves too! 

Thanks to Skeena for hosting the challenge.
