2016 Tesla
Electric motor
The 2016 Tesla Model 3 is a notable data point to flag upfront: the Model 3 did not exist as a retail vehicle in 2016. Tesla began Model 3 deliveries in July 2017, with the first public production cars reaching customers in late 2017. A vehicle titled '2016 Tesla Model 3' is almost certainly a data or title error — the actual model year is likely 2017 or newer. The specs here most closely match a Standard Range RWD Model 3, which started at $35,000 when it became widely available in 2019. With that caveat noted, the Model 3 RWD is a compact all-electric sedan built on Tesla's own platform. It's quick, efficient, and tech-forward, with over-the-air software updates that continue to add features long after purchase. The 15-inch central touchscreen controls nearly every vehicle function, which is a love-it-or-hate-it design choice. For Lake Geneva-area owners, the RWD configuration deserves extra scrutiny in Wisconsin winters. The Model 3 RWD can struggle on unplowed or icy roads compared to AWD variants. Winter-specific tires are strongly recommended. Cold temperatures also reduce battery range noticeably — plan for 20–30% less range on sub-zero days.

The Model 3 RWD puts heavy torque through the rear tires. Tesla recommends rotation at this interval — more frequently than most ICE cars. Skipping this leads to rapid rear tire wear. Wisconsin potholes accelerate uneven wear further.
Tesla uses a HEPA-style cabin filter that restricts airflow when clogged, reducing HVAC efficiency — a real comfort issue in Wisconsin winters and summers alike.
Regenerative braking means the friction brakes are used much less than on a conventional car, which sounds like a benefit — but low brake use means moisture accumulates in the fluid without the heat to boil it off. Test moisture content; replace if over spec.
Same low-use issue as above. Rear calipers in particular can seize from corrosion and salt exposure since they rarely generate enough heat to keep rust at bay. Wisconsin road salt accelerates this significantly.
Use only fluid rated for -20°F or lower. Standard summer washer fluid will freeze in the reservoir and lines. The Model 3's low nose means the front camera and sensors are constantly hit with salt spray.
The 12V battery powers all low-voltage systems. When it fails, the car may not 'wake up' or unlock. Cold Wisconsin winters stress lead-acid batteries hard. Tesla has had multiple TSBs on 12V battery life.
The Model 3 is heavier than it looks due to the battery pack floor. Combined with Wisconsin road conditions, suspension wear is faster than the EPA weight class would suggest. Check for clunks or pull.
Road salt works into the retractable door handle assemblies and accelerates wear on the small motors and pivots. A light cleaning and lubrication each spring can significantly extend their life.
Always defer to the manufacturer's service manual for warranty-mandated intervals.
The Model 3's day-to-day operating cost is genuinely low — electricity is cheap, brake pads last a long time thanks to regen, and there's no oil or spark plugs. Annual maintenance at an independent shop is minimal. The risk is the big-ticket items: MCU replacement, battery module work, or body repairs can be expensive and slow because Tesla controls the parts and repair network. Budget a healthy emergency fund for those surprises.

Similar price point, all-electric, practical hatchback for daily commuting. Better cold-weather range retention in some conditions; more independent-shop serviceable.
RWD sport sedan in similar price range. Gasoline-powered so no range anxiety, but higher fuel and maintenance costs. Comparable driving dynamics.

Smaller range but competitive efficiency, lower purchase price, and broader independent service network. Good cold-weather management.
Direct competitor to Model 3 — electric sedan, similar size and price, AWD standard. Worth cross-shopping for buyers wanting an alternative EV ecosystem.
