Just kidding! The people I seem to trust the most are the ones I've met in person. All the guys from the usual ECZA meets are absolutely awesome! On top of that I'd add the local guys I've met thanks to TT.Net.
You only know the worth of this forum when you buy yourself another car and have no clue how to maintain it, fix it, diagnose it or personalize it...and there's no one to give you advice!
