The original Scenic mini-MPV was a revolution when it arrived in 1997. By the time the new model appeared in 2003 there was a lot more competition, but the Renault is still a great car - and it's even better in long-wheelbase seven-seat Grand Scenic form. These cars offer great value as used buys, with diesel editions proving especially attractive. Some cars can be troublesome though, so tread carefully, checking everything over before buying.
