I'm a prowed owner of an E50 AMG. I bought it used. The car is a clean '97 with about 40K miles. The first thing I did was to look for ways to remove the speed limiter. I discovered later that it has no top speed limit. The beast is only limited by red line in 5th. It easily passed 280 km/h (and still pulling) when it touched the rev limiter. Great power.
