I am looking at a 1999 SL500 with 40k miles on it. My cousin works with the guy that is selling it and claims he is a fanatic about it. He is asking 29k for the car (seems like a good price). What are some of the weak links in this car? Anything really problematic? Please no references about the dated style b/c I prefer the last generation SL's looks (obviously the technology is better in the 2003's+). Thanks for any info!
