The SL500 uses an M113 5.0L 24-valve SOHC V8 making 302hp and 339lb.ft. of torque. The SL550 uses the M273 5.5L 32-valve DOHC V8 making 382hp and 392lb.ft. of torque. Note that in some countries other than the USA, the SL550 was still named "SL500", although it had the 5.5L engine.

Considering now the low difference in price of the two, i'd opt for the 550 and i'll take the extra 80hp and just a newer car, since those came out later. Overall the taillights are different, and might be some difference in convenience functions. And, if i remember right, some options on later years were added to the base model, making it with more options than the base 500 models.

P.S.

Unless you mean the R129 SL500, which is a completely different car.

Or look for an SL55 AMG for a few thousand more and get another 100+ HP. SL55 has the same 113K engine but adds a supercharger.

Not sure about just "a few thousands more", but definitely an option. All depends on the mileage and year.
