Those 14k is justified.

3k for leather.
Rim n tyres, probably cost 2k.
9k for turbo charger, intercooler, etc etc.

Totally worth the money.

There is a ratio limit to cvt box. It will be wider than conventional auto box. But now, conventional auto has 8,9,10 speed, which also has very wide gear range equal o more than cvt box. Problem is, this type of gbox only limited to more expensive car for now.
