I'm really glad to hear that Renault isn't giving up on the full size MPV after all. I've had two Espace IV's and, whilst I have no intention of buying another, the idea that Renault is likely to move the MPV game on again with a sportier, more luxurious concept is intriguing.
Jerry99 is right to suggest that most MPV drivers don't use their 7 seats all the time. However, people who drive regular saloons or hatchbacks are rarely seen driving with a full compliment of passengers either? So what? I'm sure there are Transit vans driving around all over the country with little or no cargo too. I still drive a 7 seater (not an MPV!) but I only use the extra seats occasionally (but regularly). If we didn't have the extra seats we would need to take two cars on these occasions. Besides that, I can't afford to buy a Smart car for the occasions when I'm on my own so one car will have to suit all occasions. Sorry.
do or do not. there is no try.
