I'm looking to add an CPO i3Rex as a second car to my X1 s35i; I need the i3 for HOV access and my teenage daughter will (gulp) be driving the X1 soon. Any advise on: Model year and package. I want to keep cost down and 2017 seem to be a good cutoff for technology, packages etc. Thoughts on bang for buck in later years? Also is the sport package with added pep worth the extra cost? What to look for when buying used. Likely I will buy remotely, Bay Area prices are ridiculously inflated locally. Would appreciate advise on asking for reports on battery status, other documentation of status/performance, or other questions I should ask. Scamming I should look our for when buying remotely? Price. It's dizzying the range of prices out there. 2 cars with the exact same specs can be $1000s different in price. Buying CPO from a dealer, what is a reasonable price and how much is the advertised price marked up (ie how much room is there to negotiate down). Warranty. I think the current standard is 4 years 35,000 miles? Possible or necessary to purchase an extended warranty? Charging. What are the upfront infrastructure costs to adding a charger in the garage. I'm also considering going solar since it's not going to be cheap to charge from the grid I expect. Used the way to go? With multiple incentives and rebates it seems like buying new may get the price down close to used? Are there any incentives for rebates buying used? I really appreciate any input and guidance on this!
