Well, I wrote him a letter and he wrote back... his reply follows:
Many inaccuracies? Well, OK. SL500 -- I got used to the old nomenclature. Guilty. "Key" as opposed to "fob"? "Key" is better, and easier for readers to understand, since fob is technically no better -- an ornament worn at the end of a chain? Perhaps "electronic key"?
I thought the car's ride needed some civilizing. What I didn't mention is that I drove two examples of the car -- the first went back to the barn because the fancy dampers went off-line. Some wiring problem caused the system to shut down and the car to go into limp-home mode.
I also think the car has more rattle and shake than the SL500 -- see, I got it right this time. Compare it to a Lexus SC430.
But the XLR is a very nice car, as I said. You'll be happy with your choice, I'm sure. It's a cool car. Next year's will be better, tho.
And I absolutely think the tires could be improved. Run flats are too flinty for this class of car.
Thanks for reading and happy motoring.
