If you will pass by C-5 on the way to Novaliches, may madadaanan kang shop na name ay Reibet... they do vertical doors for 50k. Medyo mahal kasi you pay for the workmanship. Its just like any ordinary door, bumubukas sya just like an ordinary door, then itataas mo. Dont expect a lambo type door na itataas mo na agad.
But then again, hindi sya advisable. I'd rather place my 50k on a good paintjob.
it also depends if your car has a kit for them. but there are some custom car shops offering this, but for a premium. 50k is an accurate estimate as posted earlier...
for me, i'd spend it elsewhere... a good rim and tire combo maybe?
