On Carousell, I saw got one post listed for ~10k in Kepong area.
Ativa groups in FB quite a lot people buying, can ask there also.

Modelista bodykit, do you mean the front and rear bumper of T.Raize plus modelista ?

Or the local make Modelista add-on bodykit on the original Ativa's front and rear bumper ?  (saw that on shopee before, but since the seller is "on holidays")

Misread, my bad. As per amdxp, did you mean original bumper or just the body kit? The ones I found are original Raise front and rear bumpers.
Is this your car? Wondering if any extra work had to be done to fit this bodykit on to the car.
