You Don't Need to Know
Doyou mean by solidifying the value used on the 3? Lexus going to depreciate at a slower rate.
User tech....don't care.Most of us here are more focused on user tech, performance, and safety tech where BMW is pretty good at holding an edge.
There is two sides to depreciation. If you buy new than depreciation on these cars is brutal. You need to know this going in. Some people will only buy new. Because depreciation on these cars is so bad it opens up a fabulous opportunity to buy lightly used. Its a lot more work to buy lightly used as you need to find the right car and do your due diligence. I looked for a while when I bought 1.5 years ago a 2014 435ix with 22k miles and 6 months factory warranty left for $29,500. This car stickered at $58,500. The car was close to as new. I enjoy my car immensely and will not take a huge depreciation hit.
User tech....don't care.
Performance...except for a nice inline 6 BMW seems more content with a decent 0-60 and Camry like driving experience.
Safety Tech....Like auto braking, self parking, lane keeping, or blind spot monitoring? I can do that myself.
BMW is a just badge now. One that tries to represent everything to everyone while doing nothing particularly great. Reliability? Ultimate Driving Machine? Prestige? Holder of value?
I used to admire BMW's for being enthusiast cars, now they are overpriced badges. They are not up there with the best luxury interiors, they are not the sportiest to drive, I don't know what they want to be and frankly, I think they don't know either. They want mass sales, that's about it. The latest ads are marketing infotainment to millennial buyers, no mention of driving experience. You can get pretty much all of BMW's tech on a run of the mill Mazda 3 these days.
With my Porsche, everything is top notch. Performance, driving experience, reliable, interior and build quality, holds value far better than most cars.
After buying the last 3 series, I would never buy one again and I don't like saying that. I had a wonderful ED experience but the car is mediocre. Sounds like then new generation is too. My car is a very comfortable, quick, weather beating, stylish, efficient four door. It is not a luxury car, nor a real sports sedan in feel or execution. There are tons of those and most depreciate much slower and have far better longevity. Especially if you have an n20/26 timing chain. The 3 series is now an expensive pile of meh.
Mercedes went through a long period of wandering in the wilderness. I think BMW is just at the beginning of a long walkabout.
