obviously the exterior is different as is the interior, revised gear ratios, revised suspension, 16s on the mk instead of 15s the mk2 has fbw throttle the mk1 has cable. mk2 has xenons, automatic headlamps and automatic wipers (light and rain sensor) the exhaust is different (two cats side by side on the mk1 and one bigger one on the mk2) mk2 has full climate a/c erm thats all i can remember
