Hi Everyone, we just bought a 2006 XLR with just 17,000 miles on it. Bought it Portland, OR and drove it down the coast to San Diego - what a great way to get to know her!! Anyway, I'm wondering about what bolt on performance enhancements you folks have done and would recommend or, conversely, stay away from. Thanks in advance - I'm looking forward to becoming part of the XLR community.
