I have just purchased an i30 SX vivid blue CRDi auto, tinted windows, after market cruz fitted properly in the steering wheel, color coded reverse sensors, just a great car, a pleasure to drive, this is my fifth Hyundai, 2 manual Accents, 1 Tucson auto another great car, and a 1999 Lantra Sportswagon manual, all bought new. So far the new i30 is returning 45.46 mpg (for us oldies) or for the rest of you 16.11 K's per litre or 6.2 litres/100 k's, It will only get better with more mileage on it, I will post some pics shortly.
Cheers
Dave
