I would say that more of us use them as daily drivers than don't. I WISH I had the money to get a daily driver and let the VX be the garage queen that I want her to be. With that said, I bought Vicki (my VX) five or six years ago (can't remember) with 35,000 miles on her, and have used her as a daily driver ever since. She now has 112,000 miles on her and has never given me a problem. I check the oil religiously at every fill up and always have to add some; usually 1/2 to 3/4 quart - she's a thirsty girl. I usually do preventative maintenance to avoid anything going wonky, but other than that she has never left me stranded.
I say go for it.
