same here, drove my frenz jazz, suspension is abit on the firm
side hence road humps and potholes are felt. insulation isnt very
good as well, at high speeds, some wind noise can be heard, but the
engine more than makes up for this, i-dsi izit? pretty revy, cars
feels quick on the go, perky drive, I wouldnt fall asleep driving
this...
as for IST, havnt driven one yet, though my neighbour owns a modded
one, looks damn fierce with its 16inch wheels.
