I have never owned a Subaru sir. But since I am on wait list for the XT, I also did some reading from other forums. From what I read from current and previous owners of Subaru cars, paint is not really a strong point for them. Some say it's what makes Subaru a Subaru, others say they are buying a Subaru, not a BMW, so it's acceptable that the paint is inferior to more premium brands.
How it compares to other Japanese cars though, that I don't know. Maybe they are saying Subaru uses cheap paint, but compared to Toyota and Honda, maybe they are just at par lang. In my opinion, you have reserved for the Forester XT for your own reasons, like maybe you liked the AWD, the technology, safety features, etc... so whether your decision will be affected by paint quality is really up to you
I think any car naman that isn't being maintained properly will age faster. As recommended by some Subaru owners, proper care and waxing of the paint is highly recommended to protect the paint of the car. I think this actually applies to other cars as well, not just Subaru.
May I ask sir what color you reserved and what date they are telling you na dadating yung unit? Thanks.
