Need to wash it properly and shoot a few then. I upgraded from a 1.4 n/a corsa (100hp) which was a 2010 model where (as I understood it) Opel changed the axles (or some main parts) to what the Insignia was using since the first iteration was shared between the Corsa and Fiat Punto so they had many issues with back axles falling apart. This alone made the car very heavy and sluggish so it felt slower than my 1.4 75hp
Ibiza I had before.
Leon, on the other hand, is a much different story. Great engine, easy takeovers, very nippy and it eats 1.5 liters of fuel less than my corsa per 100km! (My first tank showed 6.9-7.0l/100km in comparison to 8.5l/100km I had in my Corsa). And that's city-drive only!
