When I bought my Audi my ONLY thoughts leading to what to buy were :
What do I really love about this car ?? I'm going to get exactly what my HEART tells me to order, not what is more of a value now or long term. With me, buying my first Audi was a love affair...........and it remains so even today. The car is sooooooo satisfying in every way that I just don't care about what all the investment stats say to do one way or another.
Buy want really turns you on and forget all the other stuff.
You won't regret it...........not for a minute !!
Well, let me put it this way. I test drove an S5 and ordered an RS5 w/o test driving it on the same day and even did European Delivery. I'm not looking back. The high-revving V8 in the RS5 gives you a driving experience that can only be matched by the R8. The only reason to go for the S5 is if the RS5 doesn't agree with your financial situation.
