I'm just about to finalize my paperwork with the current configuration of 85KW battery, blue, panoramic roof, tech package, tan leather, active air suspension, partial shelf, paint armor and twin chargers (for possible future upgraded home charger) and 19" wheels. This totals a surprising $98K with taxes before federal tax credit. Before submitting my electronic signature, I'm looking for advice and forum member's wisdom on choosing the performance vs. base model and further thoughts on the 60KW vs 85KW battery options. I've never spent more than $40K for a car and my first instinct was initially to keep a lid on the total cost and weigh what returns the greatest value. Certainly the 60KW battery pack would handle the vast majority of my daily driving including most weekend trips out of the SF Bay area to Monterey or Sonoma but perhaps not the less frequent jaunt to Lake Tahoe, Santa Barbara or LA without some logistical planning. But the 85KW upgrade seems to offers the most flexibility to use the car for all of these scenarios. However with the more desirable options, I'm suddenly pushing $100K. (Surprisingly I found the panoramic roof, even when closed to make the car feel so much more spacious and pleasant with abundant natural lighting and as a consequence to be a very desirable upgrade) Today, I've had a chance to briefly test drive both versions at our local dealership including a short run on the freeway from one on-ramp to the first exit a few miles later. The differences are subtle with exhilarating acceleration from both sedans. However the sheer speed and raw power of the performance version is both thrilling and intoxicatingly seductive. So at this price point, why hold back? Doesn't the performance model seem justified when one looks at the long term enjoyment and ownership of such a revolutionary vehicle? Or would practicality and value ultimately guide your purchase decision?
