'Cupras' were originally rebadged sports. (basically a sport will all the extras and rebadged in the UK as a
cupra).
In fact the original cupras were £18,000 and are listed on the V5s as a sport.
It would appear that originally '
cupra' was actually a trim level thing, with sports being available and the
cupra being being a sports will all the extras. (leather / memory, auto diming mirror, auto wiper, ESP etc etc) - as extras on their own i think they would have costed about £6,000 but if you got a
cupra over a sport you get them all for £2,000 difference or something like that.
So if they say its a sport, but its got leather etc it likely to be a
cupra.
Then, they dropped the 'sport', reduced the price of the
cupra but made all the nice bits extras... so no leather etc. but did put in K03s turbo.
so, actually early cupras had alot more kit and IMO were better cars.
Due to the V5 thing many will be listed as sports but if they have leather are most likely cupras. later on they may be
cupra, but may have less spec!
