That one is surely a pre-production, with 832 serial number, maybe would be better to set it again as 1999 specifying that is a pre-series probably I listed that one as 2000 before Alex's comment, or based on plate date.
Anyway, the Lybra was introduced in March 1999 (sedan and wagon), with pre-production likely starting around the same period, and first price list is dated September 1999 for both. Sales to the public begun that month. For sure normal production didn't start in 1998, possibly the fact that the car had quite a long gestation and prototypes in definitive form were shown in late 1998 created some confusion.
