Performance is the same as any 1.3 K11, so 75bhp as standard. Spec can depend on which options is was bought with at the time. Base models are sportier front and rear bumpers with wrap around rear spoiler, manual windows and no PAS but they did come with a sunroof and boot pull/filler cap release. Other options which were available were the electric windows, PAS, ABS with rear discs, (pretty rare) and optional alloy wheels and I think a funkier stereo, which by today's standards is crap anyway lol.
Front bumpers are not impossible to find but are not common either. Matt Humphris sells them new for around £90 plus the dreaded i think, (i needed one 4 years back when I was re-building my SuperS), the harder items to procure are the front driving lamps, which are mounted in the front bumper. New, they are rediculous, like £120 each, but they can be sourced 2nd hand but be prepared to hunt around a bit.
