Well, I do see where heated seats would be nice. Honestly, I think it's a 50/50 call. If it weren't for the fact that the only 5 speed, GT within 1500 miles happened to have leather when I bought it, I would probably have taken cloth too. But, I took what they had. I don't regret it, but I wouldn't regret it the other way either.
Cash is cash, plain and simple, and you have to decide what's more important. I was lucky enough to have a trade-in valued at $15 grand, so I had plenty to play with.
