Since you own a Focus 2.0 - the only natural progression is another Focus, or downgrade to Fiesta which at least has the same excellent chassis dynamics. The Accent CRDi may have better acceleration from full stop and fuel economy but the suspension, handling and NVH suppression is suspect or at least will be equal or inferior to the Elantra which is inferior to the Focus in these areas. Besides eventually the future maintenance/repair of CRDi engines will offset the fuel savings - just ask those who have had to replace their busted turbos or fuel injectors.

Having test driven all the local variants ... My favorite Focus is the Ambiente MT sedan because it's the cheapest and actually the easiest to adapt to (assuming you know how to drive stick) - it is also the simplest and thankfully doesn't have the confusing profusion of buttons on the steering wheel. It is definitely more responsive than the AT version and one of the best MT cars to drive in the segment. I am guessing that its pedestrian clutch pack is much cheaper to replace than the dual clutch too, The main downside of course is its a sedan, but ... it's still one of the better looking ones out there. The wheels need to be replaced but at least you can choose wheels that look better than the so-so ones on the Trend. In terms of japorms - there is no question the Sport hatch is the ***iest but its pretty 17 inchers and sporty suspension are actually not ideal for our ugly roads. The Titanium model is best in terms of refinement and luxury, maybe its the posh leather but it felt really smooth and creamy.
