Price difference with or without matching numbers?
 

Hi guys,

i've got a 1969 911T but i've recently changed the engine for a brand new revised engine.

Now it seems that the old engine was matching to the chassis so...luckily we wtill know where it is, and it isn't mounted in another car yet.

How much would the price rise if we would mount the old engine back in? Assuming it would be in perfect condition just like the non-matching engine?

The car is in very good condition otherwise. I don't need a value for the car, only a price difference between matching vs. non-matching... i don't know if it is that important for a T-model.

cheers, and thanks for your answers!

I think that would depend strongly on the overall condition of the car. If the car is in excellent concours condition, then the original engine (matching numbers) becomes important. It may add 10% to the value. On the other hand, an average car with some issues it may not be important at all. As time goes on, it will become more important as fewer matching numbers cars remain.

well,

the car is in very good condition, as it has been fully restored. It is in no concours condition though.

- as good as completely original (incl. radio, seats, etc...)
- fresh original color paint from bare metal (beautifully done, haven't seen a better one yet)
- brakes revised
- engine new
- carbs revised
- suspension new (bilstein)
- new rubbers all around
- pedal cluster rebuild
- gearbox bushings done
- lots and lots of small things....

issues still present, though i don't really care (because we're going to do a 30.000km haul with it in a few monts, so it's gonna get dirty anyway:
- crack in dashboard
- dirty ceiling
- tacho and clock no worky
- carpets dirty/worn
- passenger seat a bit on the soft side
- original radio only 2 settings: off or max volume :D
- missing foglight metal plates
- some other bits 'n' bobs

We think that it is worth (in Belgium) around 25.000 EUR, so matching numbers could add a little bit to that amount. But i don't think it would justify spending 7000 EUR rebuilding the original engine...

Maybe we can keep the old engine, and store it somewhere. Maybe it will add more value later on, as you said.

thanks!

From what you describe, I'd agree strongly with your last sentence. Enjoy the car now as a driver to slowly restore. In the future, if you sell, the matching # engine will add to the price, even in it's worn condition. Your car is collectable regardless if it's "just a T" because it is becoming scarcer. The more original parts you have, the more "collectable" it becomes.

Keep the original engine. Much more valuable. Even a car w/ some rust issues are worth more w/ the correct motor.

From what I understand, the difference is larger in Eur than here in the US. More important there.

"Maybe we can keep the old engine, and store it somewhere. Maybe it will add more value later on, as you said."

Perfect. That way there is little risk of you blowing up the correct motor.
