Egress are worth a fortune NIB or new built, a lot is down to the kits being pretty rare. Collectors usually want it looking as the kit, so this is fairly cheap
http://www.tamiyaclub.com/trades_model.asp?cid=78796 because it has different tyres and the chassis is fibreglass instead of carbon.
If you want something that will get run best to stick to a modern chassis, actually running an old chassis is the fastest way to destroy those happy memories. Don't know if an Egress shell will fit a DF03, it probably can be made to fit as the original Avante body certainly can.

If you are looking for a DF03 chassis to fit the body, the Avante MkII has yellow wheels for the Avante look, the Dark Impact has black wheels more in keeping with the Egress, and it's usually cheaper as well.
