[Vehicles] 2008 Citroen C5 and 1999 Seat Arosa/VW Lupo
Citroen is self explanatory, Arosa on the other hand has three "versions", there is the pre face lift Seat Arosa (facelift was in 2001 I think) and there is a Volkswagen Lupo, all these cars have the exact same design looking from sides and back, the only difference is in front lights, Seat Arosa preface lift has one light design, Vw Lupo has another design and Arosa postfacelift has a different light design. So if someone desides to make the Arosa, they can make 2 additional vehicles very easy.
There are some blueprints of these vehicles, you can find them easily on Google.
Seat Arosa original (1999)
Arosa postface lift (2001)
Back design of Seat Arosa pre&post facelift and Vw Lupo
Some have gray bumpers like this one, but some (like my own) have colored bumpers. Also the postfacelift version seems to have a different light texture, same design and size, just a little different texture, it looks like "tuning version" lights.
