David,
Every now and then it acts up, I just send it in for tuning. Not sure what kind of system it is. It does have a smog pump.
The paint job was around 5k, but $2500 of that was to fix the door. A young woman rammed me pulling into my driveway. Out of pocket on my side was $2500 and 1k for misc. items i.e. new chrome, new rubber seals, and so on.
