Keep a careful eye out for the bodywork. Seen a lot of Terras for sale at dealers with dream machine paint jobs over the last few years.
Originality is everything on these bikes and I would take the original bodywork with some honest wear and tear over any a shiny New paint job every day of the week.
Its quite easy to spot the differences if you know what you are looking for. A couple of obvious differences are the green number boards are decals on the originals and not painted, the silver stripes are actually white stripe decals stuck over a silver painted area if that makes sense.
If you are unsure there is plenty of knowledge on here so post some pictures up.
