Excatly and if it were my £30k i'd want more than 4 pistons under the bonnet too.
Well, you won't want the Merc C250CDI as that's a 4-pot diesel. Chug! Chug!
But seriously, the days of anthing above a 4-pot in hot hatches is pretty much over (Audi RS3 excepted - though that is likely to be a run out model). Even the next Ford Focus RS is dropping down to a 4-pot.
Rumours are Merc is developing a 3-pot petrol for the next C-class!
It's just the way the world is. And you can't change it. Sadly.
