well i think you have no choice as of now i think they're the only one who have this chassy alignment machine , saturn closed due to broken chassy alignment machine
make sure you ask how long will it take to do the job
make sure ask how much your going to spend ( estimate )
and most of all ask them if they included the 12% vat on your estimate
baka magulat ka nalang meron palang additional 12% vat on all there charges including labor may 12% vat , thats what i experienced with them

they gave me an estimate and when billing came ayun na ang +12% sa lahat
workmanship : ok lang
