It's a few tenths slower than the BMW M5 '05. The more modern SRT10's are definitively quicker as well, but not by a ton.
This might be the only 1996 Viper GTS for sale in the USA right now, or at least the only one on ebay:

Only 3k miles, for $60k or best offer. That's a steal for a collector's car that will likely double in value over the next decade or two.
And the Viper is definitely not a beater or a sleeper. It's a monster.
