Some questions about the acquisition of a new RR Sport

Hello together! I am currently looking for my next car. In the narrow selection I have the Range Rover Sport Supercharged and the new Touareg V8 TDI. Of course I am aware that both are completely different cars, but size and performance make both interesting for me. I have already tested the Supercharged and was very pleased. However, I forgot the following points during the test drive, or my dealer can not really answer them. Is there not the sitting heating in the front without the heated windshield? I am somewhat disturbed by the “sliding” in the disc. – Can one copy music data to the hard drive navi? – Is the voice control of the mobile phone really limited to numbers, or can one also control the telephone book speech control? Unfortunately, I found the steering wheel control extremely cumbersome. I would also be interested if one of you leased a similar vehicle. So far I always felt like leasing as se You are cheap, but for the RRS I have received an offer (25 tkm p.a., 36 months) with a leasing factor of 1.76. With this factor I consider whether it is not more useful to buy the car. Do any of you know a dealer who offers cheap leasing terms? Thank you already in advance! konst.
