no there wasn't a r32 trim for manual air con, however, there was for the net optic trim that can be sanded down to look like r32 trim.
don't focus on milage too much. remember most mk4 golfs are 15+ years old, so even mine with 130k on the clock averages out at less than 9k a year! (also mines for sale if your interested)
also if you find one with very low milage, chances are its going to be a pita as seals/bushes etc will not have been replaced and will start to go, you may also find that common problems haven't occurred and you will have these pop up.
