I agree with Mark, Purvis Eureka. From the background certainly Essex, not OZ (although from the dirt on the front-end, I'd say it had been there at some point in it's life), and based on the ride height and obvious weight on the tires, I'd say it was sporting a 2.5l V6, likely sourced from a Mazda. Pics look to have been taken in early spring, I'd guess at April, and likely in 2009 when Essex experienced a day without heavy rain - the 4th I believe it was.
Does anyone know where David is, I hope he isn't on a flight to the U.K. to check this one out!
