The first one has lowering springs but prob still has factory shocks, that's $1000 off the price. It has aftermarket exhaust, another $1000 off the price. For 10k its a good deal but it is white
The second one has a replaced engine, WTF is up with that? You need to know if it has a salvage title or is a flood car... Regardless a 99 ain't worth that much. I would offer 10k for that one as well assuming clean title.
