Do I need to go back to the Honda dealer?

My 2012 Honda Jazz/Fit had a noisy manual transmission and was difficult to select the lower gears. Honda replaced under warranty everything inside the gearbox (it took 4 weeks to get the parts from Japan). It is starting to make a sound like a bus again and is hard to select 2nd and 3rd again. This time the dealer said they all make this sort of noise (but wouldn't show me one of their cars making this noise!).
So my question really is, 'How do I make them fix it again?'. It's still under warranty.

Btw: I have always driven manual cars and never had a problem. It's definitely not me.

How to get this nut off of my alternator?

I changed the water pump on my 95 Honda, the ONLY thing that's keeping me from finishing the job is the alternator pivot bolt is STUCK and won't budge.

When I removed the old pump, I was able to wiggle the alternator loose just enough to slip the belt off, but now that the new pump is installed, the alternator won't budge even a tiny bit so I've been unable to put the belt back on.

To top it off there's less than 2" space between it and the wall of the engine compartment, so my socket wrench won't' fit. The only other tool I have is a flare wrench, which I tried several times and it did nothing but strip the nut edges considerably. Soon there won't be any shape left to the nut. What can I do to loosen the nut?!

It's the one sticking out beneath the water pump pulley in the center of the photo below (it's enlarged so it might look like there's more space to get to it than there actually is, there's less than 2" in front of the bolt). It looks like I'd need a socket wrench to have any hope of loosening it, but I haven't found one in any of the stores I've been to that will fit. It's driving me nuts.

What are some affordable cars I might like?

I'm going with my dad to test drive some cars tomorrow, and I'm trying to create a list of cars I might be interested in test driving. Even though I'm planning on buying a used car, I'm buying the car myself, so it needs to be somewhat affordable. I tend to like cars that look unique and different. Here are some styles of cars I like:
2013 Volkswagen Beetle
2013 Chevrolet Spark
2012 Kia Soul
2013 Honda Fit
Mini Cooper Countryman
