SC2SOARER

Hello everyone! Just purchased a 93 SC400 and am loving it. Had a couple questions for first mods. First of all the car only came with two keys, none with remote. Since I'm planning on getting an aftermarket alarm I decided I wouldn't bother spending 500 bucks on new keys. I am looking for what you guys think the top of the alarm system would be around 500 bucks. Hoping to get auto start, trunk release, valet parking, and interior sensors with paging system. Are there any others than Viper and Python or should I just go with one of those.

Also I wanted to gey my windows tinted. Everywhere I go here in Arizona is charging me around 300 for removal of old tint and new one installed. Any shops in AZ that would do it for less? What if I removed my own tint, anyone know how to do this properly w/o damaging my windows? I appreciate the info and happy to be part of the community.
