I heard that members of this forum may be able to share some friendly advice. I'm looking to buy a 2005 to 2009 slk, probably the smaller 2 liter one. Considering I'm not much of a mechanic, would anyone be able to share some practical tips, like what I should look out for and what the risks might be, especially if I were to buy from a private seller or an independent reseller? Thanks in advance!
