1. Did 2008 E320 Bluetec sedans customarily come equipped from Mercedes-Benz with a mounted, full-sized spare and wheel?
   
2. Does a "glow-plug" indicator light illuminate in the starting process?
   
3. Is there an accessory block heater available for the 2008 Bluetec from Mercedes-Benz?
   
4. Where is the battery for this car, in the trunk, or under the right-rear cabin seating cushion?
   
5. Is the rear window deck power-operated sun shade an option, or part of an option 'package' when the vehicle was ordered?
   
6. The 2008 Bluetec I'm considering has a red colored, Mercedes-Benz logo, 110AC plug-in meter of sorts, with alligator clips for the car's battery. Without further inspection of this apparatus, was this a unit provided by MB factory/dealer (as included) when the car was bought new? Is it a 'quick charger' or is it a 'trickle charger' would you surmise?
   
7. I am obviously just shopping this 2008 Bluetec sedan car at the time of this thread's creation. The absence of a spare - any spare threw me for a loop over the weekend while viewing the car, so I had these other Qs too.
