Family of 4 with an 18 month old, 4.5 year old, and hope for more kids down the road. Currently, one of us drives a 2019 minivan (60K mileage) with the kids to daycare and work - commutes 15 miles daily. The other drives a 2013 commuter (165K mileage) to drive 170 miles daily. With the tax credits next year, we wont qualify for the tax credit next year but Tesla is offering a $7500 break if you take possession by end of year so we are feeling some pressure to buy and secured a 5 seat Model Y. However, knowing we want to expand our family, we were looking at the 5 vs 7 seater for extra seats. Should we proceed with the 5 seater or wait until our commuter dies and get the car we need at that time (knowing we wont get any tax credit or other credit)?
