try E240 Avantgarde b4,
transmission not very smooth,
tiptronic respond slower, maybe it's the best at W211 time gua...
But, V6 sounds very chun and looks also not bad...
and yeah, SBC is an issue that need to be concern.
Maintenance sure higher ma, Continental car ma...
for avangarde, more electronic component = more problem lo
previously run it on RON97, but, too expensive, now using RON95.
so far, no problem yet...
E240 with 112 engine,V6 SOHC engine,precise combustion with 2 sparkplugs for each camber(all 6 cylinders make 12 sparkplugs in total) more reliable engine..you might wanna try E230 or E280 with AMG package..the pulling,so damn stronger but this 272 engine well known with balancer shaft wear out and engine no power after sometimes due to intake variable shaft break off..
