Dual motor version - snow, compacted snow, fluffy snow, slushy snow and 24 different snow versions more. Ice, did I mention that? (unfortunately will not tolerate price above 4000€).
Smaller 55kWh battery pack - definitely overkill for me, but due to pretty cheap price per kWh I'm happy with that huge pack as well.
Model3 will not offer air suspension and even if it did, I will not take that. But adjustable dampers, maybe (if price appropriate).
Glass roof - only if 1) it doesn't open and 2) it has an integrated manually or electrically operated full shade (not mesh) - because, cold, don't want extra weight for mechanism I rarely use (have that on my other vehicle) nor heat the cabin like crazy.
non-leather interior, also not cheap cloth - either synthetic plastic/polymer or partial leather, definitely not black.
cold weather package - still cold you know... I really hope to see heated windshield here. Would be worth 400€ extra.
Not sure about sound system, need to listen the base version first, definitely not interested if costs more than 800€. (BMW offers two upgrade options for M3-competitor, 400€ and 1100€, latter is opted less than 5%, hope Tesla won't overkill that one)
Smallest possible wheels - because I love driving comfort more than looks. Also running costs. Might choose turbine if budget allows.
Cheaper onboard charger - have lots of ChaDeMo's and house is already a huge sucker so nothing above 1x3kW or 3x2kW will work.
Non-black nor 50shades of gray vehicle. Blue is my preference.
Premium package is hardest for me because I don't know what it will offer. I don't want automatic liftgate. Either tinted windows or integrated mesh shades would be very welcome. Upgraded headlights, maybe.
Not sure about towing package - need it few times per year and I can use appropriate vehicle. Only if cheap. (1000€ on BMW, no go for me).
I don't need roof rails. I don't want spare tire. But I do want two sets of carpets - velour and rubber.
Model 355D please. Blue. Thank you.
