My Mk1 had Viper through foglight, Chip, CAT off back box (v6 style), RL Traction Control. The reason I sold it was the clutch and gear box were on their way out, and it was beginning to feel generally worn, I got such a good deal on the cup that I couldnt really turn it down.
I would have been in my Mk1 still if these hadnt been such a problem.
