as far as i know, my focus has been amazing. I test drove the civic and if you want more interior noise go with the civic, it also has less power but u get the paddle shifters
if u want the corolla u get most of what the focus has but it loses out on the good looks of the focus, and ofc again less power
focus for me was my choice because i got a good deal, worked out the cheapest and had the best build quality + features i wanted and i liked the looks...
Very personal but imo go focus... i'm owning mine for about 4 months an love it.. so i know where ur coming from
this is unbiased ofc..
