Superb MY10, MY11, MY12 differences?

[WSDsmurf]

Hi Guys.

I'm new here. Have been trawling the forum a lot as I am thinking about buying a Superb Elegance wagon as the next car.

For the life of me I can't figure out the differences between different model years of Superbs.

MY10: +DRL in foglight surround, +sharkfin antenna? (from Briskoda)
MY11: +KESSY available (option)? (from BriSkoda).
MY12: +bluetooth, +front/rear parking sensors on sedan.
MY13: +park assist on sedan.

I did find the following about confirming model years, in that:
"It's the 10th character in the VIN, in our case, our VIN is : TMBKB93T7Cxxxxxxx.
The C indicates a MY12, B = 11, A = 10, 9 = 09, 8 = 08."

I understand MY12 was the first to get standard bluetooth, is that correct? (That seems really late to me).
Was looking at an Elegance MY10 wagon, but can't find much that details what changed from MY09 to MY11 etc.
But I gather that despite it having a RNS510 sat-nav, that bluetooth isn't standard?

Any pointers would be helpful.

Thanks.
