I've put about 13K or 14K miles on my ERA over the past two summers. There were a few things to be worked out due to the Cleveland engine and EFI since these aren't normally fit, but got those things squared away the first year. I wouldn't be afraid to jump in the car now and travel any distance with it.
It's a comfortable car to travel in and I do run it back and forth to work a fair amount. The ride is surprisingly not harsh at all and it doesn't wander around on bad roads even with 245 front and 335 rear width tires.
The biggest thing I've found to be a hazzard is dragging the front of the car or directly under the seats while going in and out of gas stations and side streets.
The amount of thumbs up you get while driving is surprising, especially from motorcyclists. (I have a bike too and wave at other bikes, but rarely cars)
Cameras and picture phones pointed at you while in traffic or at stop lights are fun too!
Everything about the car is first class as I'm sure the other manufacturers car are too. As has been stated many times on the forum, each potential buyer has to weigh all the options out there and pick the manufacturer that is right for them. I doubt you could go wrong with any of the cars currently being offered. 5 or 6 years ago, there were not quite as many offerings, at least ones being advertised on the Internet.
Like the other ERA owners, I love mine too.
