I personally wouldn't bother with one for a daily drive, its still a mk3 Escort so not really that 'nice' to drive and to keep it in good condition without a garage will be labour intensive. The novalty will soon wear off.
I Love 16i's and will have one as a toy if and when my S1 finds a new owner. Imo they are best left as a second car living in a garage as they are also a bit spesh now. The british weather will soon turn it into a swiss cheese.
How about something less criminal as a daily like a Mk5 or 6 RS2000 or if you want something older a S2? Although some of the above 16i points also apply to S2's.
