lotusforsale is correct, it is less refined, but if you like to tinker, it's a great platform for modifying. I've built mine to be quite different from stock, but I am constantly amazed at what people have done to theirs. Different engines, transaxles, interiors, body work, frames, just about everything. This happens even though the car hasn't been in production for about forty years and there were only a few thousand made.
It's very light - I had mine weighed on a truck scale at 1600# with me in it! I really think it's probably a little heavier than that, but anyway you look at it, it's very light. I think the only street cars that might handle better might be a 7 or an Elan.
On the negative side, there are no door beams so it is not a car to be t-boned in. It's very low so it puts your defensive driving skills to the test - especially with all the SUVs on the roads. If you're really tall, you might have a problem, but then the body is fiberglass so you really can fix that!
If you drive a Europa, you are guaranteed to get a lot of comments and looks. Very few affordable cars garner the attention a Europa does. They are almost all very good buys. For whatever reason, they have not had the price appreciation that other Lotuses such as the Elan.
In the end, it's all in what you want. It might be just what you want, but if it isn't, it may not be for you.
