I really think they're good cars. Yes, raw and brutal are the two words that everybody uses to describe Vipers. That's exactly what they are when you are either 1.) at full throttle and beyond 100 mph or 2.) driving on the ***-hole infested roads of Baltimore. If you are driving within the realm of, oh say, the law, it's quite a pleasant car. I have a Gen 1. The windows are curtains that you have to install and the top has to be unrolled first. Both are very easy tasks. (And I don't get wet with them on, even in torrential rain--which I try to avoid, but hey, can't predict the weather!) Other than that, they're very comfortable cars. I drove mine home from Detroit (to the Baltimore area) with my dad in one day. We flew out in the morning, and drove home that afternoon/night. We felt GREAT at the end of it! Cruise around in sixth gear at 65 mph and you're burbling about at 1,000 RPMs so the engine isn't taxed and neither are you. The seats are great, the interior layout is a hair shy of the-best-ever, and it operates as smoothly as any other good car.
The thing I hate hearing over and over again (especially from "experts" who have never actually driven the car) is that it has a "REALLY HARD, ER, GRRRR, SHIFTER TO MOVE. GOTTA USE YOUR WHOLE BODY TO, UGH, HURL THE MASSIVE SHIFTER INTO ITS NOTCHY PLACE!" That's bull cookies. The shifter is fantastic! I have the stock leather knob on mine (not the ball) and I'd have it no other way. It's also right next to the steering wheel, which is the perfect location. Yes, the Miata (let's always draw comparisons to that car) has the "perfect" gearbox. I've had three of them and, yes, they do have perfect transmissions. But they also have 125 horsepower. You know, actually, let's draw a comparison to that little car. Miatas are great. The Viper does everything a Miata does, but it's all stepped up a few notches. More power, more grip, more size. But both are light (for what the Viper is, it's light), nimble, and fun roadsters.
You WILL NOT be disappointed. Go get it, and don't look back. And don't listen to people who have never owned one.
EDIT: You know, if I didn't feel like I was committing blasphemy by doing so, I'd daily-drive one.
