I made a new spoiler from lexan and some modified HPI wing mounts. It's tougher than the original and easily repairable. Doesn't look as nice but it works well and it will hold up better should the car go flying through the air again.
I have tried multiple times to purchase the Killerbody Lancia but their website just does not work. I managed to make an account on their main site, get the body into the shopping cart and complete the checkout process. The only problem is, it never asked for a payment of any kind. Their USA site doesn't have online shopping. The prices are very reasonable for that amount of detail and all the stuff the bodies come with, they just won't sell me one.
