My standard mk3 1.6s handled like a boat.
I'm faily certain these used the same running gear/suspension/arb setup as the XR2is. Dunno if the FRST was different still?

My standard mk4 escort handles really well for what it is. (base model running gear, 1300). I was quite impressed when compared to other similar aged vehicles I've owned in the past.

Given the choice I'd go for an escort over a fiesta mk3 but not necessarily over a mk1 or 2. Imo the mk3 is the weakest of the fiesta line in terms of driving experience.
