GLC 43 Coupe vs. Porsche Macan vs. BMW X4M40i
New here. I'm cross shopping these three cars. I need to find one that fits in my garage with 93" doors (so the BMW X6 is out). I'm attracted to the gorgeous interior of the GLC 43; the Macan and X4 have very dated interiors.
Any input as to this? Do people like their cars? Reliability?
Thanks!

The main concern with the X254 GLC 43 is the not reliable enough e-turbo, and a bunch of other powertrain technology that still requires fine tuning. The main issue I seen reported are very random check engine lights, that are caused by mainly software but occasionally hardware as well. For example casting material remaining on the pistons causing issues. Software issues is mainly MBUX and all sorts of glitches.
The M139 engine is relatively reliable if without all the technology, such as the system used in the A-Class and CLA.

No MB 4-banger is ownable or leasable because the engine is a grenade waiting to detonate. Transmissions are clunky and no good - read this site extensively. Good interior space. Nice aesthetics. Terrible dealers and dealer experience. AMG suspension gets criticized for harshness.
Macan base with EA888 2.0 4-banger is an anemically slow dog with a tiny rear seating area. Macan S with EA839 3.0TV6 is peppy, not fast, with a tiny rear seating area. Both engines are generally reliable. Macan air suspension is by far the best suspension in this segment. Water pumps last 50k miles or less. You couldn't give me a PDK - I don’t like how they drive and they are appallingly expensive to repair out of warranty. Good dealer experience. Trustworthy CPO warranty.
X3M40i is a great all rounder. It is the lowest brow model in this comparison. Good engine and transmission. Roomy front and rear seating. Suspension gets criticized for harshness and exhaust for loud droniness. Interior nice but not the nicest in the segment. Good dealer experience.
As mentioned earlier go with the lowest mileage GLC43 with M276 3.0TTV6 from the prior model generation and own it as long as possible.
