Here's some info on the Golf Highline

"In late 1995 VW launched the Golf VR6 Highline, a limited edition based on the standard car but only available in two colours, the normal Diamond Black Metallic and the very unusual Purple Violet which has never been used on any other UK VW. Both came with air conditioning as standard and matching leather interiors. Yes that does mean purple leather but thankfully it was very dark and not that garish. The carpets were also a dark purple and came with matching overmats - thankfully the dash was black though. A wooden gear knob was standard and other little tweaks were the body coloured tailgate spoiler, the smooth rear VW badge, smaller 'VR6' badges, the higher rear section of the centre console (also used on the Vento VR6) and extra door seals. An oddity of the Highline is that it doesn't come with the plastic sill covers fitted to all other VR6's. All VR6's lost the wheel arch trims in October 1995 when the side repeaters were changed to an oval clear lense but some early Highlines pre-dated this and have the rectangular orange lenses."

Had the same 174bhp 2.8 engine as the std Golf VR6 - that's not to say that someone hasn't put a bigger version in ...
