Yeah theres a benz and infiniti dealer on the same street so test drove both same day when the 30 came out a while back
The primary mechanics and chassis are the same so maybe some service parts prices may differ gotta run some online reviews
On a separate note ...
Cant believe that heavy rear hatch is manual good grief ... cheap cost cut move
They did use the 45 shifter instead of the column stalk ... too bad they didnt keep the 45 engine
The drive and suspension characteristics are totally different ... they really wanted to be different from the gla and it shows in more bad ways than good
