So, since people are asking for a bug free, decently indented, 0.2 operational version of PEN1:LS, I'll just make this release for fun 
I take absolutely NO CREDIT for anything in this script. Every credit goes to Denver (Astro) and him only.
What's new in this version?
- Added join messages and leave messages (with reason).
- I heard there was a /me exploit, but I think samp 0.2.2 fixed that already, so no need to do it myself.
- Fixed cars respawn delay
- SetPlayerArmour in houses (/heal) which was bugged in the original pen1:LS. For some reason the /tv off stuff was replacing the correct code, I debugged the whole command.
- Fixed car eject bug
- Added RACE checkpoints
- Fixed the minigun ban. It will ban the user with a minigun. If you want to take it out ask in this thread.
Ok that's all nice and fun but what's new in this version?
- Tweaked up and upgraded "/carupgrade" command, adding an autotuning system to the script.
Available cars go up to level 30, but like I said I take no credit for anything here (it is made by me though ;)) so feel free to edit the heck out of it in any way you want, release it under your name, I don't care.
List of available cars:

EDIT: Debugged version in the link above, removed some models to make sure even with ALL the cars in carupgrade your game will not crash.
Enjoy
