Great data, BP, I think you'll have a few more to keep you busy, as they are still in production. It looks like the latest 135is coupe is VY60545 - Alpine White. They are up to VY60549 in 135 production thru 7/5.
I was using
http://www.bmwarchive.org/vin/bmw-vin-decoder.html to see if they built mine, (which they did on 7/4).
My dealer said I had to get him the order no later than 6/15, but I see several others here have ordered later - have they officially cut off the order taking?
