Having trouble deciding..which one.

 

I would get the VDP Super. More room, same power and nicely appointed.

I don't know if the Super's suspension is the same as a regular VDP - if it is, it may be more "comfortable" than a regular XJR, that would be your choice.

I would have liked a little more rear leg room in my XJR. I don't really care about the picnic trays though.

If you think the 100 is going to be a collector's item, I truly doubt it, but if that is what you want, then buy it.

depends what you want out of it, if it's the 4 door version of the XK then the 100, if swanning about with the old folks in the back, (but with a mean streak) the VDP.

I will say the 100 is the best of the 308's but I do have the best one on the planet

 

The VDP Super has the same comfort suspension as the regular VDP. Beginning in 2001 it is fitted with the adaptive shocks system but these are the comfort adaptive shocks not the sport adaptive shocks offered on the XJR. It does not have a rear anti-roll bar but it does have the larger front brakes from the XJR

 

If you like it Black and sinister get the XJR100

 

I have never driven an XJR, but I have driven a Vanden Plas Supercharged.

My XJ Sport can handle horsepower a lot better than the VDP S/C, it has no
rear anti roll bar, so the rears don't like WOT on anything but perfect surfaces.

It is a super-sleeper car, and it is fast, but it is only quoted at 16/21 and
slurps another 1mpg. Also, remember it will be slower, 5.43s to 60.
(XJR-100 does 16/22 mpg)

The VDP will be cheaper, easier to find, and less of a worry... with no
rub-strips on the sides, the XJR-100 is a magnet for jerks with shopping
carts and/or Dodge Neons. The VDP is bound to attract less police
attention too!

Tough choice. If Someone gave me $22,000, though, and I had no debt
(Obviously) I would go for the XJR-100 I think. I love the wheels too
much. Not to say that the 17"s on the VDP don't look great.

Like the others have said, choosing between the two depends on what you want out of the car.

Since both cars are approximately the same weight with the same powertrain, the straight-line acceleration will be the same.

The VDP S/C is a softly sprung luxury car with room in the rear for adults. They were fitted with CATS (at least in the U.S.) from MY 1999; make aggresive moves with the throttle, steering, or brakes and the damping levels firm up. The brakes are the same as a standard XJR, so you can find parts cheaply. The VDP S/C was available in all x308 color combinations. Standard VDP features like picnic trays and more wood-veneered panels inside. Seats are mostly flat to accomodate larger drivers and offer little side support.

The XJR-100 is more stiffly sprung to provide a higher level of handling, also with CATS variable damping. Because of the SWB, don't expect to put adults in the rear and keep them happy. The cars look great without the rub strips, but also susceptible to door dings. The XJR-100s came with special Brembo brakes, which are not cheap to replace. The XJR-100 is available in only one color combination, black over black with gray-stained wood. Watch out for the special wheels and their easily-damaged trim rings. Seats are more confining than the VDPs, which in turn offer support in cornering.
