The Civic HX would be illegal to sell now because it won't meet crash safety standards. That's the point: you can get a car now that weighs quite a bit more than that HX, performs far better in a crash, has significantly lower emissions, has much more passenger space, and still gets the same fuel economy roughly (i.e. a larger/heavier class of car is getting the same economy as an econocar that's now too small and unsafe to be sold).
