Happy new year one and all! It's now January which means it's almost time for me to get my SL55. So I've been looking at autotrader (every day!) and it seems that there are quite a few for sale and quite a wide range of prices. ie. I see a 2003 model with 70k, black and pan roof and mid-range alloys for £13k. A 2004 with 70k and no pan roof, mid range alloys for £16.5k A 2006 with 70k, silver pan roof, mid range alloys for £22k. why the huge disparity? £3k per year of manufacture on the above. Also, is it cool to post links to auto trader here? (I don't especially want the dealer to see what I'm saying, especially when I ask you guys how much i should offer...) thanks!
