Cadillac XLR – oh we barely knew ye

In 2004 Cadillac introduced the Cadillac XLR (Experimental Luxury Roadster).  Featuring an enhanced Corvette chassis and the Cadillac Northstar Engine, the new XLR was the very first car available with the magnetic MR suspension.  I covered the XLR in detail here, but I love these images of the final, 2009 XLR;

And what a luxurious interior:

It is a sort of standing joke that as soon as Automobile Manufacturers really get a model ‘right’ they cancel it. Farewell XLR.

On the other hand, welcome to interesting future used car value.  With low production numbers and wonderful appointments, the Cadillac XLR will be a unique choice for years to come.  Certainly not a car you will see everywhere.  The V8 model with 320 hp has adequate power, and of course the V Series model is available if you need more.
