for A/C: the 1300,1302,1500, and possible the 1200,vw engines are capable of having A/C.,
for the parts, it is easy to find,. since we have shops here that could provide you the parts u need for the bug., and
a good beetle unit now a days, with AC would most probably cost you not less than a hundred thousand, unless if it is really detailed interiorly and exteriorly, watsover,. then it'LL cost you obviously about over a hundred thousand pesos...
personally, since i'm still a school boy, i've learned to appreciate and really took extra value of the beetle since the time we bought it until now. honestly. i am a big Car enthusiast and i really love customizing cars with all the available resources in the modification world,
i love the beetle compared to the 90's or the 80's modern cars for a reason that i admire the unique look of the car,(turlte look) hehe, and is truly strong in terms of the body and engine considering its a vintage car..., more over, when you have the beetle customized to its extent, i tell you,.,really!!! it is so beautiful, and for me, it really makes a big difference among all other cars,.,
