Hello SL – driver drives a 98 SL320 R129 and plays with the thought to switch to a SL500 R230 from 2003. I would like to know the pros and cons between these two very different “cars”, regardless of the performance of the engines.Of course there are already SL drivers who have changed and made their experiences with them.Question to those who have travelled both types over a long period of time: keep R129 or exchange with R230 ? Ciao
