Fujimi 1/48 cars?

I just found a bunch of old Fujimi 1/48 cars in a local shop. That's right, 1/48 scale. I was surprised they even made these. The cars were
old subjects like the Fairlady 240Z, 240ZG, Cadillac, and so on.

Has anyone built these before? Are they any good? I have built some 1/43 plastics by Heller, and if their quality is typical of 1/43 plastics,
then I guess I'm not terribly impressed.
