A small rock fell from an overpass and hit my mazda 3 right between the two doors. Natanggal ang paint and the metal is exposed where it hit.

Casa is going to charge 12k (6k per door). (both doors got the chipped-off paint).

Is their price reasonable? If not, please recommend a good reputable shop in Manila where I can get this repaired! Thanks!

(edit: casa also said it would take 5 days)
