It depends on you. What do you want. 30 ponies ain't much, but it is 20% in this case, if I did my seat of the pants math correctly. You get more than just the larger engine for your $2K.
The 2.0 has done the job for a long time. Many say to the level of mediocrity, but it still got done.
If I had it to do over and had some choices, I'd have done the 2.5, but the 2.0 has does everything I've asked to this point.
I didn't get out of a 600 HP turbo diesel, but the sedan had a little more. Well quite a bit more, than both of them. I haven't been disappointed, but my needs fall in other places than HP or fast starts.
