Yes it is important you inspect your vehicle prior to tendering payment. What if there are scratches/dents and most importantly unfit issues, which are lot for MX. All these items need to be put on 'Due Bill' and signed off by both you and Tesla DS, so that it can be corrected and remain documented. Check wheel alignment as well, as mine was off. Another thing I discovered on a hwy driving over 80MPH, the passenger side front small window is lose and makes a noise which you will not discover during delivery, unless you take it on highway and test it while radio is shut. Now after driving for 3 weeks, many issues are discovered with the sensors in general, specifically, FWD. They are big pain. Doors do not open all the way up even though there are no objects around them. It doesn't happen all the time, but unfortunately happens when you don't expect that to happen. Another issue I discovered is, dead big screen when turning on the vehicle, as I had to soft restart three times within two days. Hope this helps.
