ok,, I use this car as my daily driver... I have a 2005 GTP, it currently has 47000 miles on it... I only use the highest synthetic oils when i have the oil changed.. I keep up with my car.. ... If i do everything right, and dont run it hard... Just the few mods i want.. such as,,, Rockers, headers, ported Blower, Intake, intercooler, MAYBE PULLYS.. How many miles can i expect from my baby... I am going to own this car till it dies.... and please, tell me anything and everything i need to do to keep my car running for a hundred years to come...
