Guards Red on Black 1983 Porsche 911SC Sports Carrera extra clean 37,500 miles

Hello there!
I am selling my collector caliber, turn-key, very well-sorted, California, Guards Red, original paint, original black sport seat interior, original engine, numbers-matching 1983 911SC (that was a mouthful!).
When purchased, it was a very nice, original car, but not quite up to my high standards. It had a $20,000 service performed last March to bring this car up to the next level. It has only been driven about 800 miles since then. Among the upgrades and maintenance that the car received: 930 hydraulic cam chain tensioner upgrade, ported and polished cylinder heads with new valve guides and top quality machine work (bringing the engine power up to around 215 horsepower with the exhaust system upgrade), SSI stainless steel heat exchangers (great performance upgrade), Dansk 1974 Carrera exhaust system per SSI recommendation, new complete factory clutch assembly (since the engine was off the car, not due to wear), new Bridgestone high performance tires, oil cooler upgrade, rebuilt brake calipers with new seals along with new brake pads and rotors (due to age rather than wear), and a WEVO short shift kit.
Weighing only around 2600 pounds, this car moves very well now, even by modern standards! There are many other individual items which were serviced I can let you know about upon asking.

The car is in Monrovia, CA now, please let me know if you would like to arrange to come by and look at it.
Thanks for looking!
