wow 12-13 in civic thats remarkable, we had 2011 oriel prismatic for a month didn't know past history but it was brand new at the time never got above 6.5 in city, mine is 56000 driven in black in maintained like a queen, every maintainene done before time especially since its driven hardly 20km in a month, annual milage if there are out of city trips is 2000km
i also have 2010 altis cruisentronic sr, and personally i like driving this one, it seems to have more torque and response plus power to weight ratio is better, and the hydraulic steering is much more responsive than electric steering, though the new one has better grip on motorway is bigger and more fuel efficient and has better initial tip in on the throttle
i especially like the Ac and the extra big and wide seats of this model they have better thigh support plus visibility is great, what tyres do you plan to upgrade as you are not happy with bridgestone potenzas? i have yoko advan db 195/65 and they are awesome really quite and really god grip especially breaking and no wheelspin on acceleration good start, however at next change i think 195/55 r15 would be better as currently it feels a bit high
