If you chose to have a pre-purchase inspection, I would recommend a block test. If a boot is leaking, it usually causes check engine light/lean codes, and may have higher than normal idle. Visually, there is no way of telling if the inserts have been installed. Visually, with some specifics, you may be able to tell if repairs have been performed. Retainers broken, new cotter pins in ball joints, etc, just some of the tell-tale signs that someone has been there. You would not know how far the repairs went. You may have options in buying from private party, where they know the repair history, and may have receipts to prove it. From a dealer, sometimes the car is a trade-in, and most times it was bought at auction, so you may or may not have repair history. If you are looking toward a Cad, they never had a 3.8. A 3.6 came out in 2004 CTS, and SRX, wasn't until 2005 that the STS used it.
