I believe the Viper system has that trunk opening optional. But I recommend
CrimeGuard 745i, because its the cheapest system with loads of features...such as keyless entry, start kill and even pages u if someone is touching your car all at the cost of $200. But if you want to go all I would recommend the
Clifford AvantGuard 4, its has way too many features....well to many for me...I think it cost around $400-$600.
