Scale models

Can somebody give me some good links where I can find Group C an Gt1 scale models?

thanks in advance

Check at Tamiya.com, They have separate websites for Japan, America, and Europe. They regularly produce the best and most detailed kits in the industry. I know they do the Mazda leMans winner and the Toyota GT-One as well as many Nissan GTPs and Skyline competition cars. They also do a Porsche 956 and 962 leMans car.

You will never be disappointed with a Tamiya model kit. Nothing but quality. They build em right in Japan.
I have put together a Ferrari (older) F1, and a Tyrrell F1, plus I have put together the Mazda 787 RENOWN. They are sweet!!!
