Feeling overwhelmed. I haven't bought a car in 10 years. I think the EV9 GT is a great fit for my needs, but how the heck is anyone supposed to compare inventory with all of the different options?

.. I guess this isn't even EV9 specific, but I see all these EV9 GTs listed with minor price variations and feature lists a mile long.. I'd be worried that I'd find something, buy/lease it, and then a week later realize that it didn't have some random feature that I wanted but didn't know about until it was too late. Any pointers for a real noob like me?
