I've thought about it, actually. Phoenix rush hour traffic. Last time I counted (I get pretty homicidal), I use the clutch about 200 times each way. Considering it's about 25 miles and takes just under an hour, that's clutching about 8 times per mile / about 3 times per minute.
f*** that. If 464 had any collectible potential, I'd be giving serious thought to a 4B11/SST swap.
