Welcome to Three Arches in Cardiff. The garage, originally established at the Llanishen Cardiff site in 1936, was taken over in 2000 by former main dealer Peter Dutton. We can cater for a wide range of vehicles for routine servicing, MOT testing (Diesel & Petrol Class 4) and general repairs such as clutches, exhaust systems, timing belt replacement as well as general maintenance. We also carry out routine servicing for cars still under a manufacturers warranty in keeping with manufacturers guidelines.
