That ferrari engine in it needs ferrari money to fix. And from experience I can tell you that it takes only a little tiny oomph to strip anything on a ferrari casting.
They also are bastards when you try to buy a spare part. And it has a hilariously short service interval.
the transmission is the same 6spd ZF from BMWs - which I service with Ford Mercon SP (cheapo) - its failures are documented and proven too - they are not proven in Pakistan because they require advance level diagnostics to find the issue. They are not too bad to be honest.
to top the cake - its italian from a mess of other italian and some german parts. That doesnt sound good.
While the benz and BMW powerhouse tourers are stupendously powerful and have proven reliability.
