Recommended Posts

So after having a great time at another charity track day, it got me thinking about tuning my Westfield.

I got on eBay looking for upgrades and then ended up buying another one......as you do, along with a trailer off gumtree. Good times.

Meet Westie part deux. Some of you may Remember it as Richard Greens old car.
