since you mention it, i also cant find them on protons website..its a walk-in kind of service centre, for normal service is ok..but they dont have anything else extra to offer..when i need to change to new tyres, i did ask them but they cant do it...they also never mention about aircond service to me...so, for normal service is ok lah (plus its convinient to me too)...i would really love to send to cose tho
