So i thought id share the link: http://grumlt.citrina.lt/autos/konceptai.html
Unfortunately not any info on the cars and it wouldnt be in Engligh anyway, but facinating to see the pics.
I do like the 'Xanae', a Xsara/Picasso looking concept designed in the earlier 90s. It was based on the Activa chassis so had the ARCS system. It had the 2.0 16 135bhp petrol engine, wrap around rear seat, turning captain cheairs in the front and a non-symetrical body style with one door on the drivers side and two on the passenger, on a suicide door.
Excellent idea!

I actually have a road test of this in an old directions magazine.

The C-Air Lounge is another intersting car. Very lovely looking car/MPV thing.
