Re: I know a few people who put in their orders.
"Personally, I usually don't buy a car that is in the first year of a new model."
As the adage goes, never buy version 1 of anything.
Every new vehicle goes out with known issues and many more are found as cars are lost in accidents or been in for repair or servicing - structural faults, safety issues etc.
So anyone who buys a car which has been out for a couple of years and fixed these problems gets a better, more reliable car. Aside from that the vehicle editions tend to improve in time offering e.g. the Model S got new battery options that early adopters won't ever see.
