Probably a little bit off, but I always gather my facts as much in advance as possible. I've been having some engine probs with my vehicle, and am considering one of these: I like Cadillac, and this would be a few years old and, thus, affordable. Does anyone here have one? Are they reliable, fast, good to drive? Thx! ...and I have CR'd them, CadillacForum.com'd them, etc. I'd just like get the straight poop from y'all)..
