Hey I thought I'm the only1 like that. Anyway nice see another clone . I think the reason for that is we want to drive a perfect ride with its best condition. So we build it out from the crap to cool n of course we keep it cool as long as we own it. So who ever buys a car from such guys are the luckiest.
I know some places for parts. I went 2 a place recently and they had lots of astina parts. Its easy to find external parts for astinas than BG5S's since there r losts of astinas comparing to 323 hatch. The most hard to find stuff r the itzi bitzi titzi parts such as ashtrays, switches, handles etc. Parts as such r cheap but its like finding a needle in a haystack.
I'l try my best to help you out.
