My 70D is in for service today and they gave me a p90d with ludicrous as a loner (holy crap it's fast). both cars were built in 2016 and both cars have similar miles on them but the p90d seems to have a better build quality than my70D-no squeaks or noises or rattles and just seems tighter overall. the seats seem more comfortable as well. Am I imagining this? It also has latest software which restricts autopilot to the speed limit. I was literally honked at twice because the flow of traffic was greater than the speed limit and people were looking at me like I was a granny driver. I refuse to update my software because of this. The 5mph over seems like a perfectly reasonable compromise. Not sure why they got rid of it ?
