If you can see, this mod calls "Lada car pack" so this mod pack includes only vehicles that are related to Lada, Fiat 125 is not related with Lada
Well... Pack includes the Polski-FIAT 125p already, which only shared the doors with the FIAT 124, and, consequently, the Lada 2101. The western-european version of the 125 was fairly similar to its polish counterpart. It's probably out of scope, but it would be a relatively simple addition.
Pumped for the lada 2105 riva, my grandfather had one in Trinidad. Sorry for the abhorrent quality but this is an advert for them from IN trinidad.
Honestly looking back on it, this is a shocking price. 50,000 for a brand new car, even back in the 90s was fantastic
