Just to try and sort the confusion over sport packs all uk spec sport pack cars got:16" Wheels, lowered suspension, Side skirts, Carbon dash, Leather Steering wheel, Red on black dials, and optional large boot spoiler, and seats as noted below:.
SP1, Blitz cloth sports seats.
SP2, Recaro cloth sports seats.
SP3, Momo leather seats.
Just to bring things into perspective, at the time the standard cars had either metalic effect or wooden effect dash, (Both NAFF!), Steel 15" wheels!. The Lusso got the 15" Alloy Wheels, wooden dash and wheel UGH!, Velour or leather seats, Climate control on the 1.8 (Standard on 2.0, and 2.5 anyway)Black on white instrumentation.
The Sport pack system was superceeded in may 2000, when the Veloce spec cars arrived, the spec of the Lusso and standard cars was upped as well.
I hope this doesnt confuse things further, and as far as I know it is correct for UK cars of 1.8, 2.0 nad 2.5 engines.
