I'm new here...as this is my 1st post! I bought an 05 STS V-6 w/the sport luxury pkg w/ 28K miles. It has every single option that caddy had to offer in 05. I was wondering...well did I get a good deal? I paid 25K for car. Also is it a good car? My wife talked me into this deal so I guess I need reassurance or did I just get ripped? Oh, are there any performance mods for the v-6 I looked but can't seem to find them for the six'r? Any help, comments or suggestions are welcomed!
