I'm getting pressure on this forum to buy one; while, in th real world people are telling me, "do not buy a Hyundai!" Of course these people are largely uninformed, but attorneys in Southern California simply do not drive Hyundais (unless they're in their 20's and fresh out of law school - I nearly bought an Elantra 10 years ago, but people probably would have frowned on that too).
The locals are expressing their disapproval in advance. I can swim with the current or I can swim against it. Still deliberating...
I see what you're trying to say.
I think the Genesis will fit in with the other luxury vehicles pretty well.
Ride is smooth(although some owners tend to disagree), interior's fit and finish is pretty good, and the sound system is just awesome.

All this(V8+tech package) for under $40k OTD is a VERY good value.
But then again, there are a lot better cars out there for more money.
If money was no concern for me, I'd opt to get an Audi/BMW/Lexus/Jag.
Other lux/sport sedans that I drool all over;
- Audi A8/S8: Just beautiful. Elegant, classy. B&O sound system is pretty good, I hear. Although a lil harsh.
- BMW M5: The ultimate sport sedan. Can still have a lot of fun while being practical. Manual transmission availability is a huge plus for me.
- Lexus LS460: Very well-made car. Although I don't see the appeal over the Equus other than the "L"
badge.
- the new Jag XJ: Some don't like the rear, but I love the way it looks. Interior is awesome!

- 2011 VW Phaeton: Looks like VW is being brave again and decided to bring over the '11 Phaeton to the US. Awesome car, unjustly underappreciated car.
- Porsche Panamera: Lots of people and the press seem to hate this car, but I LOVE it.
Your colleagues will not like the fact that it's a Hyundai, but if they get to see the vehicle in person, I'm sure they'll be impressed.
It's up to you. I'd say go for it, but if you're comfortable spending some more $$, why not get something better?
