Consumption of sporty LEONs

Hello, wanted to buy a SEAT LEON at the latest after the training in 2 years, Vllt. but already next year, because my car might not come through the Tüv due to front damage, a SEAT LEON. I stand between 2 variants: the 1,9 TDI with 150 hp and the 2,8 V6 with 204 hp! What do they cost the so in maintenance? Does one z:b: what the 2,8 so in time?? I would also like to know if the 1,9 TDI also has a very good engine sound, because it is very important to me!!! Thank you in advance… MfG
