Vixen RV.

NMNA.  Too bad it's a fixed top, most have a pop up area that's hinged on the passenger side - makes standing room.

BMW turbo diesel with a 5 speed.  They fit in the average garage.

I want one of these, but yeah, fixed top is a deal breaker. 

Also nicer for camping.

I think parts are unobtanium. May not be practical if you want to do RV things on a regular basis.

There's one of these slowly rotting in the front lot of my local german car specialist. Super neat machine, but if he isn't fixing it it probably can't be fixed.

The long defunct BMW dealer that was in our town sold them. 

They could also be had with a Buick 3800 and GM automatic trans, certianly better for sourceing drivetrain parts.

First photo is the first Gen of Vixen.  Second is the later model with a fiberglass roof and GM V-6.  The V-6 overheats and the roof won't allow you to get through a normal 7X9 garage door.

Oh yea. Love the conversion van style roof, and have a love for a 3800. And have owned many things didn't fit in a standard garage door. The warehouse I lived in  several years had a 12'W x 14'T door...
