Longevity question
So I have a question about the longevity of the C7 Corvette. My cousin is an extremely talented mechanic that can take apart an engine and put it all back together again in a week. I've been asking him about purchasing my first corvette. The C7 to be exact and he's very bent out of shape on the fact that thousands and thousands of dollars have to be put into a corvette around 40,000 miles of use (aka transmission, tubes, pumps, and sometimes even the engine just needs to be replaced). However; I've been on the forums and most corvette owners are still really pumping their engines at 100,000 miles. Does what my cousin say have a ton of truth behind it?
Thanks!
Thanks!

It's a pushrod V8, a descendant of the 1955 265 ci original. It should EASILY do 100K+ for miles with reasonable service. Your cousin is FOS. He's talking about a Ferrari or other exotic. This is a Chevrolet.

And the current engine won't be very happy with 20 weight oil either 
Design, technology, and metallurgical knowledge have all increased markedly since these early engines and as long as some incredibly foolish modifications aren't attempted the engine will be fine out beyond 100K.

I think probably your cousin is too involved to take a general view. My guess he works on older engines because only older ones need his attention. The cars built probably at least through the nineties couldn't easily make it past 100K without some serious attention. Anyone who lived through those years has first hand experience. But in the last couple of decades cars have experienced a large improvement in quality. It's not at all unusual for a car to get 200K with no problems at all. And it's not just Toyota and Honda any more. Modern manufacturing techniques have led to reliable cars. I have had zero problems with the last half dozen new cars I have purchased, and I fully expect the same experience with the vette. After all, I got an M7!
He's not as smart as he wants you to believe.
