It can be done.
Best option is to buy a set of second hand seats which are heated.
U will need the buttons and fascia.
Also needed a wiring loom.
I done this on my a class and it cost in total £320.
But I had while Astor black leather.
Just buy bit by bit when it's on eBay
The wireloom from merchant was £32
All I had to do was hook it up to a 12v live and a earth.
Easy lol
