The first rides I gave were to a friend, his wife and their kids. The boy's first question, "Is the engine of this car in the back?". Not too many eight year olds around here would think to ask that. His sister got in the back seat and with a big grin on her face proclaimed, "This is a sweet ride!".
Took both kids and mom for a little ride around the neighborhood. Didn't get much above 25 because it was all residential but just the engine noise from 0-25 with the top down had them squeeling with delight!
