After almost 2 years just did our first long trip (11 hours each way). No noises detected, but previously had a few 5 hour trips to prep for a distance run. Amazingly averaged 27.0 mpg and 71 mph according to OBC. Had worried about seat comfort, but it was no problem, thankfully. And yes, black cars
do get dirty!
Oh, and was glad to discover one piece of roller luggage fit in front trunk.
And most importantly, we are Godparents now.
