I might buy an s2 cover and butcher it to fit.
Make sure it's a cover off of a Toyota powered Elise and not a Rover one.
The Rover powered Elise one has a more low-profile gear lever construction with all the cables attached at the bottom and won't fit over the VX 'high mount' cable style lever and also the handbrake lever is mounted a little differently.
Toyota version should have a good chance to fit over the gear mechanism in the VX though. May need some adjustment/tweaks but it should be fairly similarly sized.
