sounds normal...welcome to the world of a used car...Pontiac or not...GTP or not...honda or toyota, these things wear out...who knows, can you afford a new car payment? w/ insurance? and taxes? really a personal choice...I also didn't read about anything major happening either...

Advice, when something breaks, try to fix it right away...one thing breaking can lead to other damage as well. Do the best you can. sounds like a money pit? nah, not really...I didn't read anything major or too costly... Also remember if you MOD, you're taking away factory performance and can almost guarantee more issues but isan't that with just about any modded car? are you leaning tword go fast mods or things that will only give you future security? such as things that are high quality and will last or only help the motor insted of more stress...

My opinion, get out there, fix it, keep it maintainced...
