I hear that. I used to hang out at the auto hobby shop w/ my s10 blazer 4X4. Not like I wanted to, but the damn thing had been so neglected. I figured wtf, it's got a new motor, right? Wrong.
So my Marine buddies knew I was something of a gearhead, and when they hear that you know something about cars they just bring you anthing w/ a motor... Let's see, I swear I did 5 year's of maintenance on my gunny's 5.0, replaced the axle bearings on my buddy's Nissan 4X4, the list goes on. But it was worth it to me because I got to work on different types of vehicles and see how they went together and spread some knowledge to some people who were clueless.
On that note, I went to see the newest Fast and Furious movie, and here's a snippet of the conversation that went on behind me.
"So, I bought it knowing I was going to replace the motor (talking about a '96 Camaro he's just gotten that overheated on the way home)."
"What are you going to replace it with?"
"LS-1 V6, they're badass. I'll probably put a six speed and ceramic heads on it, they run real cool and should help with the overheating".
I wanted to turn around and f with him, but it would've been too easy.
Anyway, back on topic. Bottom line, those military base auto hobby shops are totally worth it!!
