What an epic Westfield, and only 1000 miles on her! Someone’s getting a bargain 

Good luck with the Sal Dean

Any videos of the car in action? Long way for me and many other potential buyers to check it out. BHP per tonne must be mental! 685 bhp tonne?

If car doesn’t sell over winter I’ll take it to the local track or insure it on the road and get some videos.
