Wasn't really sure where to post this but here goes.. Am I right in thinking that these two cars have different weights? According to Parkers: Seat Arosa 1.0 MPi 3d= 864kg Seat Arosa 1.0 3d= 880kg VW Lupo 1.0 E 3d= 946kg VW Lupo 1.0 SE 3d= 971kg Question is, are these figures correct and if so, will they have any noticeable effects on things such as acceleration? http://www.parkers.co.uk/cars/reviews/facts-and-figures/seat/arosa/hatchback-1997/dimensions/ http://www.parkers.co.uk/cars/reviews/facts-and-figures/volkswagen/lupo/hatchback-1999/dimensions/
