I know G-MANN's first question was for the adverts we hate the most but ill add the ones i like the most, soem of them are:

2007 advert of the Seat Ibiza
http://es.youtube.com/watch?v=26WcG04KGkA very "realistic" and close to audience.

2007 advert of the Renault Mégane:
http://es.youtube.com/watch?v=nSl0KKvv8rs very very original, a shame that you cant understand the lyrics, probaly youll find it odd not understanding it.

2007 advert for the Nissan Note:
http://es.youtube.com/watch?v=aotGnA2PULA very original as well

Honda Accord advert broadcasted three years ago or so (?):
http://es.youtube.com/watch?v=IccrXVULN28 another one very well planned

Advert of the Peugeot 1007 from also three years ago or so i think:
http://es.youtube.com/watch?v=VjNLFH0BIJo very nice as well in my opinion, pay atention (if you havent be fore) on the modified Peugeot background cars, they are funnily modified

Advert of the Peugeot 607 from last year (?):
http://es.youtube.com/watch?v=b683wJ4FWeg poor little cars hehe

2007 advert of the Ford Mondeo:
http://es.youtube.com/watch?v=yjH4g2lLxAY very nice indeed

2 years old (?) Opel Astra advert:
http://es.youtube.com/watch?v=jbuyjUr1CAI this one is actually for the english market but the one made for the rest of Europe was practically the same but obviously chaning the logos of Vauxhall for Opel ones, still i nice CGI advert, though we cant see it entirely here, a shame, but most of it shown in the other version is shown here as well

Citroën C4 advert from last year:
http://es.youtube.com/watch?v=45EOPbVcD3w similar to the parking one but even better for me

Nissan Qashqai advert:
http://es.youtube.com/watch?v=AyVlCoecJp8 adorable very imaginative as well for me

Advert for the brand-new Audi S3:
http://es.youtube.com/watch?v=tRcTg66BCd8 once again another original advert

Peugeot 206 advert from few years ago:
http://es.youtube.com/watch?v=E7eOVpBCtPo this one was a very good one as well

Well that's my resume, as you can see i pay too much attention to car adverts as i love them, specially when they are very well done, oh just the last one!

BMW X3 advert from last year:
http://es.youtube.com/watch?v=GAkkhX7iggw very original, BMW adverts are not known for showing their vehicles in much of action in their adverts but i think they are well thought, at least this one.

Shamely cool adverts are always cut to half its original length, on the other hand it is better as some of them are really too long and you get desesperate to watch the end of the series you are watching in that moment for example, but anyway some of them are really nice to watch, i could keep adding adverts ive liked during the years to this list but it would take more time as i have liked tones of them during the years.

I found it rather unusual and funny in a way, but indeed it is somewhat disturbing. On the other hand, crashing Renault Modus is maybe a good thing

The commercial for the new Renault cars Lots of crashing new cars. See here: Renault commercial

Ok, In the states there's an Infinti I30 (1996-2001), but not a Hyundai.

They probaly won't sell it in the states, but here is a link to it:

http://www.hyundai.co.uk/newCars/i30/

What's a Hyundai I30?

The new Hyundai I30 advert with those dogs....

The purpose of advertising is to encourage the viewer, not bore them. Compare it to the old Taurus Adds from 1986:

Maybe you will find these boring, but don't you see how more entertaining and encouraging these commercials are than today's?

that hyundai ad is imho awesome - I laughed at it when I saw it for the first time so hard

What a boring ad indeed.
I hate this kind of "nice family" thing (like slogans including texts like "share moments with those that you like", "protect those that you like", etc.)
