This is my 7th red SL in 25 years, so I'm pretty well pre-sold. I really loved my '97 SL500, but the 2003 is really a joy, and no more messing with the tops. On a 50+ mile trip at 65MPH it clocks better than 24MPG, goes to 15-17MPG when "romping" on it, but hey, that's why we buy red sports cars, isn't it? The CD-based NAVI stinks compared to my 2007 ML AMG, but you can't get lost in an SL anyway. As always, gets lots of eyeball, and is fun to drive! I've also owned Porches and Jags, but like the SL best. Worth every penny!
Performance & feel. Onlooker's awe of car, eyeballs are always on it. It just feels really good after a tough day, like a mini-vacation
Mercedes needs to improve electronics on all of the newer models.
