I actually really like it! Nice and cool in the summer and feels awesome. Had a friend with a Gt500 with the half alcantara/ leather wheel and it did show some wear with 8k on it. Mine is a weekend car so hasn't been used much.
The alcantara doesn't really wear much... but it will get matted and dirty from dirt and hand oil. Clean it up once in a while with warm soapy water and it will come back to life.
