I just ordered a White Q5 and have 2 days to change my order. I ordered the premium with 3.0 but no S-Line. I have the Audi Drive Select with 19" All Season tires. Should i have ordered the S-Line with the 20" high performance and then get the 3 spoke steering wheel and cosmetic changes or stay with what i have ordered. I also ordered the 1000 Watt stereo, entertainment package. Is the S-lIne worth the changes. Thanks.
