Automatic bonnet / boot supports

[CdRsKuLL]

ok.. please dont flame me for not searching but I dont know what there called so cant really do a search. I was just wondering if any one had sourced / found some automatic supports that will lift / close your bonnet boot via a button on the dash.. I'm assuming these would need to be a hydraulic thing with a controlled motor. I'm also guessing you wouldnt need a reservoir because it would just go back in the other end.. a sort of hydraulic ram type thing may be. Something similar to how the honda accord estate can open and close its boot lid.

thanks
