Look for the UCF11 instead of a UCF10 if you have your heart set on first gen.
That being said, I would probably recommend looking for a second gen or newer. As JDMDreamer mentioned, there are more parts for the second gen, at least that was my experience with mine.
Mine was a Celsior so it had the rear reclining, massaging seats and clothe interior which was sort of neat. The 1UZ is a good engine but I found the car to be pretty bad on gas, it got a little annoying after a while. Also, super comfortable to drive but not very exciting which I believe is the point of these cars.
I did wheels, Aftermarket air-ride and eventually a vinyl wrap on the car. When I sold the car it went for $5000. That being said, I lived in Sask and the market here for a car like this is non-existent.
