All 16v had the red 16v badge on the front grill. The anniversary additions had the deeper front spoiler, as on early GTIs, 16 inch BBS alloys, a red insert in the bumper and door trims and smoked front fogs and indicators, as well as interior changes. They are quite a bit different to look at, as they look IMO a bit meaner than standard 8 and 16v. As on the earlier post have a look at the anniversary register website as there are plenty of pics online.
