>>28460906 (OP)>so what are they like to live with?Like an Italian 3 Series, but less fat and better handling. Double bone front, multilink rear, and optional adaptive dampers and LSD are some of it's more "enthusiast focused" party tricks. Even the earlier models can be optioned with adaptive cruise, blind spot, lane departure warning and all the annoying nannies you shouldn't care about (but that nu-car buyers do, adaptive cruise is nice thoughbeit)
>I heard you should avoid the earlier years due to electrical issuesSecond most of what
>>28460933 says, any issue with the earlier years is solved with a new battery and at worst by having a few spare relays around. Carplay did come about for 2018 models however, and can be added in 2017s with an aftermarket module. Earlier years did have shittier panoramic roof parts that fail, it's an expensive dealer fix but not an impossible DIY if you're not a wrenchlet.
>Is it even worth picking a non QV up?If you can swing for a QV, you should. Ferrari-derived motor and all that. A non-QV with the sport package still makes an excellent daily driver at a fraction of the price however. With a piggyback tune on one, you're looking at a sub 5 second 0-60 from a car that can still hit ~37mpg on an extended highway cruise if you stay out of boost. Impressive for what it is IMO, but if you're looking to build a rocket for highway racing I'd look at something different (I have a V8 AMG for that).
>What are some things one should know before buying one of these?Different years have different suspension heights for some reason. 2017s were low, 2018s sat higher, and I think they found a middle ground after. Cooling system also has some plastic screws that commonly fail, you're going to want to upgrade those to metal before you get a scare from burning coolant.
Try to snag one that's still from a single owner with some history before they start reaching neglectful owners and you should be fine, there are some with 150-200k+ already.
