^^^^1) German Heritage
2) British Heritage
3) Years of performing with base model line in that price range
4) The snobbish status symbol provided by car of the above pedigree.
As was stated multiple times, Cadillac has to offer more for less - that's my opinion and I'm sticking to it. Some exact features, same exact performance numbers, and I'm going with the "other guys" every time if I'm spending that kind of cash. I'm not alone in this.
2014 E550 4Matic base price around $60k with $10-12k in options. 4.3 0-60
2014 CLS550 4 matic starts at around $70,000. Loaded I believe a bit over $80,000. I'd spend $80k on this car or wait a year for a used one before spending $70,000 on a Caddy, and I LOVE my V - LOVE it.
2013 S6 AWD $72,000 and really more of a true V competitor - way better Performace thana Vsport. 3.7 0-60
2014 550 start at $51k but in true BMW fashion I'm sure options out to $70k. I'm not a BMW fan, and I think they are overpriced and not better quality than Benz or Audi.
2013 Jaguar XF supercharged $68,000 XFR $84,000 - neither is a slouch and has one of the nicest interiors I've sat in.
The Vsport is priced in the range of all these cars and doesn't offer more for less.
2014-2015 SRT8 300 loaded at $55,000. The bargain in this price range. Would destroy a Vsport 0-60, however probably not on a track, and is really more of a 750, S class size car - they are quite large. The 2015-2016 SRT8 will have an 8 speed transmission with an optional 6.2 supercharged hemi with a rumored 600hp. This might rival the V3 at a significantly lower price, without the track inspired handling, and in a larger car. Pricing will be lower than a Vsport fully loaded.
