How much damage am I doing?

This is why buying a stick tranny Mirage isn't a great idea, it totally goes against the purpose of the vehicle.

Uhh, no. Mitsubishi sells them with a manual transmission option because some people prefer the simplicity and direct control that this offers. This is how people with manual transmissions can get better real-world fuel economy than those with CVT, sometimes as much 5-10mpg better. It doesn't "totally [go] against the purpose of the vehicle", that makes no sense whatsoever.

A potential huge repair bill is always looming should one borrow a car to a friend or if the owner is a first time manual driver. And should you decide to sell 90% of the buyers say" Oh no, It's a Stick!"

No offense, but you're talking out your rear. A manual is almost always cheaper to fix or replace, because it's built to allow regular adjustment and clutch replacement. Automatic transmissions are incredibly complex, and because of this the cost to replace is often less than the cost of repairs. Factor in the labor costs, and I'd much rather pay for fixing a manual transmission than a CVT.

I've taught several people to drive stick in my car now, and I'm still on my first clutch.
