1987 Alfa Romeo Milano - low miles time capsule

I have a Milano 2.5 with 59k original miles. Time capsule car (was in climate controlled storage for 17 years). I have owned it 5 years. All original except for:
- centerline headers (no cats)
-IAP rear suspension upgrades
- ansa exhaust
The car is in excellent overall condition. Full service history including recent major work to rebuild rear end - all new bushing, ebuilt tranny including all guibos. Everything rubber has been replaced. New timing belt and mechanical tensioner. New headliner. Absolutely NO RUST. Drives solid - no vibration, o play in shifter.

There are some issues:

- tear in driver's seat (seen in photos)
- broken indicator light in front
- key stuck in ignition
- starts and idles great, ut can run a little rough until warmed up. Typical old car stuff. Runs great once warm. Engine is fine - I have results from recent compression and leak down tests

Please feel free to ask specific questions.

Edited on Dec.1: suspension kit was incorrectly listed as "centerline" - changed to "IAP". Updated exhaust info to clarify there is NO catalytic converter on this car.
