Last fall I had a direct
comparison of 115i vs. PS-5000. Seemed the 5000 was a magnitude more powerful than the 115, but
with a decent muffler mod the 115 came close up. Nevertheless the 115 is an aged construction and doesn't have a chance to beat
its successor. And this is stated by a die-hard 115i-fan!
In Germany the 115 has been available until fall 2018. Late 2018 I had to order a 115 from a dealer in Austria
since in Germany it was NLA but I wanted to put one of the last ones onto my shelf.
