Be aware that engine wear increases exponentially as the rpms increase. I have a 1960 190 SL with a THREE main bearing crankshaft. I routinely cruise the vehicle at 4750 rpm. On the raceway there are times that I've seen the tach at 7,000 rpms. The car has no rev-limiter. This is a 40-yr-old 3-bearing engine with a 6,000 rpm redline and the engine has over 300,000 miles on it. The metal and engineering in the newer cars are better by many orders of magnitude.
