What's the range you're searching on there? I think I did a 500 mile range when I searched Cars.com for my GTI, lucky me it was only a ~7 hour drive to Ohio to get it, which I felt was tolerable.
For that matter as an open question, how far would y'all travel for a car? I think if the drive is 8 hours or under (with some short stops for food) I'd be game, if it's a car I want at a reasonable price, particularly if it's in the configuration I want. I'm not too big on flying and I really prefer driving for the sightseeing, but if it's like a 10-12 hour drive for something I can confidently fly out and drive back, I'd be up for it. Definitely not alone though, after a certain point the joy of driving alone kind of drops off.
