Oh man, a Viper, you'll be even more of a baller in that! :biggrin:
A Viper should be fine. There are speed bumps and such but not too bad. What you need to worry about are the ramps up the parking decks. The first clue that they are pretty bad is you'll see a ton of scrape marks at the edge. I did rough up my side skirts once on a speed bump at the entrance of the MGM Grand parking deck so it is possible. The TI parking deck isn't too aggressive so I think you'll be ok.
I have seen quite a few Vipers around town (four of them with over 1,000 WHP actually) and you can even rent them on the strip. Also keep in mind that if you ask and tip well, most valets will either let you park it yourself or park it right in the very front area if you choose. Valets here are pretty used to high end cars, unlike most valets for, say, a typical restaurant or standard hotel. The do drive like maniacs though, check out the Mandalay Bay for example, you'll see them screeching around corners as you enter the hotel.
However, here are some caveats:
1) Don't announce where you'll be staying. Normally your car should be safe. But I have heard of cases of people who browse car sites for that kind of info (or car meets etc.) for easy opportunities. If I was a theif, I'd just look for a Viper at TI and if you announce that you're going to party at say 10PM, then I know to jack your car then. It's a good thing you haven't said "when" you'll be there. Make sure you don't.
2) If you do bring the car up, park as close to the elevators and on the floor closest to the casino level. I know it sucks to squeeze your car inbetween other cars, but there is usually so much traffic near the elevators at all times, it makes stealing a car much harder. It's also usually better lit, and has more cameras in that area (you'll see them). It's tempting to park on a very high deck far away from everything else, but then it's itching to get broken into.
3) While it's nice to have a bad ass car in Vegas, driving on the strip is very difficult (traffic). You'll often opt to just walk to your destination. In which case, you'll car will just sit there for the entire trip. At that point, it might as well be a rental car. Exceptions: If you plan on travelling off strip, going to the Hard Rock, Palms or Rio.
4) The roads to and fro Vegas can be pretty crappy. You will get rock chips. If that sort of thing bugs you, then you may want to leave the ride behind. Speaking of bugs, there's some of that too. Your car will be dirty by the time it gets here. That bothers some people too, and seriously a sweet ride like that needs to look clean BUT do you really want to come to Vegas to wash your car?
As I was saying before, if you can truly not stress over your car, it should be fun to have. Especially if you plan on going off strip. The weather here is nice now, and I can show you some killer roads to really let the Viper stretch its legs. You can get away with so much more in Vegas than you can ever dream of in Cali. But the last thing you'll want to do is stress over your car, or have an "incident" on your vacation. The strip is safe, but that's not to say things don't ever happen. Let's put this way, people walk around alone, in the middle of the night, all over the strip, and feel perfectly safe. How many other cities can you say the same for?
Again, hope you have tons o' fun either way you decide. :smile: If you have other questions or want some personal advice, feel free to PM me.
