i'll go for the new ones for these few reasons:-
- newly developed body would be much more stiffer and stronger
- newer engine design, more power, save petrol
- bigger space(tech shrink many things)
- NVH would be impoved
overall, new ones should be better than the old ones but..... my main concern is the engine electronics... can normal service shop maintain it or need "special" diagnostic equips to do it
