I was also considering the Genesis 2.0T, largely because I'm a huge RWD fan, and the overall concept of the Genesis Coupe reminded me a lot of my first car (a Nissan 240SX). I had high hopes for the GC, but the test drive was a huge letdown:
1. The car I test drove was a 2.0T with an automatic. I would've preferred to drive a stick model, of course, but it's all the dealer had. The engine was terrible, and I'd go as far to say that it wasn't much smoother or more refined than the 2.4 liter truck motor I had in my 240 (albeit more powerful). I'm sure the car was fairly fast, but it didn't
feel fast. The automatic wasn't my cup of tea either, but from what I've heard, the clutch and shifter combo isn't anything to write home about either.
2. The interior was extremely disappointing, especially when comparing it to Hyundai's own friggin' Genesis sedan (whose interior is done worlds better than the price differential would indicate). I can see how it might appeal to the boy racer crowd some, but even there, I doubt many would prefer it to the GTI's. You'd have to be nuts too, in my book.
3. As far as handling goes, the GTI just felt more fun and exciting to me, and perhaps even more balanced (i.e., less understeer in steady-state cornering). Definitely a surprise for me, especially considering that I've never owned a FWD car because of the generally high levels of understeer.
If I were to consider a GC at all, I'd look at the V6 model, but that's just me. And if I were to go that far, I think I'd find a few extra thousand to consider the 370Z. But what I really want is a car more in the mold of the 240SX, which is what I'm hoping the FT86 will be, if and when it comes out. The GTI will more than suffice until that times comes.
In short, I'd definitely go GTI over the 2.0T GC, even with the reliability concerns of the VW in mind...
