Pretty excited about Tesla bringing me a vehicle to test drive this coming Thursday. I have had over 50+ vehicles at age 42 and cannot wait to compare. I know even if I like it, I will have a huge decision as I would need to get rid of my 13 Alpina B7 to get the Tesla. I am actually thinking I would get a pre-owned P85D. Had S550, regular 750Li etc. Currently own an M6 also. Usually end up getting them at a good price on Ebay so I do not get beat up too bad when the time comes to sell. I have been reading and reading. Finally time to drive one. I would love to hear from someone who had a 7 series to compare though. Not a lot of good comparisons when searching other than the looks of the vehicle which helps in no way.....Just had to get it out there. Thanks in advance!
