Opel's iconic Kadett 2.0 GSi Superboss turns 30 this year, and to celebrate, you can now pre-order a new SentiMETAL T-Shirt sporting this uniquely South African little rocket.

Born to beat the equally loved BMW 325iS "Gusheshe", the Superboss is a true South African icon. Featuring a trick limited slip differential, Schrick cams and loads of Irmscher suspension bits, the Superboss was a fearsome racing machine, particularly in the hands of Mike Briggs, who used it to clinch many a Group N victory and championship.

You can also buy an A2 or A3 Limited Edition print (only 50 in each size) featuring the Superboss, here

"We've been informed by local Superboss fans that a special birthday party is planned for this iconic machine, which is increasingly coveted by collectors. Keep a close eye on our social pages as more information becomes available," says Hannes Oosthuizen, SentiMETAL project leader.

"Our new T-Shirt is the result of many requests from the Superboss and bigger Opel fanbase," Oosthuizen explains, "and it is now available to pre-order here." Offered in Small, Medium, Large and Extra-Large, with an image of a black Superboss on a quality light charcoal shirt, it should be a real head-turner.

SentiMETAL, Cars.co.za's growing car-culture sub-brand, acquired a Superboss two years ago and restored it to Concours condition. View the video on this project, below;
