cars with non original engines, What affect on value does it have? Options

[dw914six]

If I am looking to add another 4 cylinder 914 to my garage, some of the best examples do not have numbers matching engines. At some point the PO of these cars has wanted more power and upgraded to a more advanced engine.

My question is what happens to the price when the engine number is not original to the car? Is there a rule of thumb?

(I know it's market driven and anyone can offer any crazy amounts (IMG:style_emoticons/default/wacko.gif) for a car they just have to have)

I'm just looking for the norm if there is one. Is it something like current market value less 25% for non originality factors?

Any thoughts? (IMG:style_emoticons/default/confused24.gif)

Honestly, I don't get the whole facination with the matching numbers, date codes, ect.
I know everyone wants to assign a value to everything but other than identifying a part it's just a number. Im sure I'll go to auto hell for saying this but it seems sort of boring.

I plan to build my car the way I want, with the engine I want, drive the living shit out of it and when I die I don't give a flying fuch what it's worth.

No trailer queens in my garage.

Absolutely. Can't understand why anyone would suffer a wheezing 1.7 for the whole time he owns the car so he can achieve optimum resale value. If that's you then here's another downer, if you really want the maximum resale value then stop driving it now. More miles mean less value, so NO MORE MILES. But why own a sports car and not drive it? To hell with that, own it for the optimum driving experience, not for optimum resale value. If you're looking for an investment vehicle then stocks, fine art, real estate, a massage parlor franchise, lots of options better than a 914.

To each his own, of course, but for god's sake drive the thing, put miles on it, have fun, that's what it's for. And to rub a little salt in the wound, if you insist on that tired old 1.7 for the resale value then know this: MY CAR IS FASTER THAN YOURS. In fact everyone else's car is faster than yours and we're all having more fun, too. A LOT more fun.
