Purchase decision I30 Premium or Style

Hello dear Hyundai enthusiast, I am currently facing the difficult decision to get me a new I30 BJ 09/17 with the premium or style equipment.The engine is the 140ps TGDI 1.4l I just wanted to ask you what you have and what your motivations were? How lively is the engine before and after the update that has changed the response behavior etc.? However, for me the most important 2 questions are How is the LED light with driving light? And how good are the assistance systems really, how annoying are they and do they really work?This is particularly interesting for me in terms of the dead angle assistant, from when this triggers Furthermore, it is important for me that the track hold assistant does not intervene as strongly as for example with the Kia Sportage There are problems with the technology up to now? Currently I have a 7 golf without the whole technology, but this is only still in the workshop and I therefore want to have a reliable new car. hon with the I30 PD stood in the workshop and how was the service, how about car rental? I thank you in advance and wish all beautiful holidays in advance your Ghost
