The Seat Leon is an attractive, affordable family car that comes well equipped as standard. This is the 3rd generation of Leon and is based on the VW’s MQB platform. The new car is shorter and lighter than previous generations but has an extended wheel base making it roomier inside. There are four petrol engines, 1.0, 1.2, 1.4 & 2.0TSI, and two diesel 1.6 & 2.0 TDi. SEAT has covered all the bases here, but the 1.6-litre diesel is the big seller in the UK.
