Summary: should I not change an RoW speedometer / odometer from kilometers to miles? Will this create mileage doubt / affect resale potential?

Relatively new here, and I'd appreciate experienced thoughts on this topic. I have an ROW / JDM 993 Turbo that is now living in the States, and I suspect it's unlikely to be exported any time soon. It has a very nice repaint in a non-factory color (Riviera Blue), which I love -- but I know purists won't value it like factory paint, so I'm not super worried about maintaining bone stock specifications. It's not a crazy expensive garage queen (and has 50k+ miles). However, I'm continuing to invest in the car and want to preserve value.

I'm considering two additional items: it has white gauges which I'd subjectively prefer to be black like the interior. Also, while the odometer is documented and seems fine, it might be smart to replace the plastic cogs / risky parts before they fail.

I could presumably do all of this with a reputable shop like Palo Alto Speedometer and improve the legibility and aesthetics of the gauges while de-risking an odometer failure (which would be a headache, and seems like an eventuality with these cars).

Making these changes (speedometer conversion, odometer conversion, gauge color change, preventative part replacement) seems like a win all around. Will I regret this if I have to let the car go at some point? Will buyers be hung up on non-stock changes? I like to keep things in good shape / well documented for painless resale. Thanks!

I should note that these items are *not* mandated for import, given the 25-year rule (and it's already imported). In fact, I'd probably be ok leaving the speedo / odo alone if the other items (gauge color, preventative maintenance) weren't tempting.

I personally would keep it original euro form but then again my wife is Germany great looking car

I have a RoW 964 that I drive frequently, previous owner put in a custom gauge dial with MPH on the inside dial which is super helpful.

Also, if you have an OBC you could also swap just the OBC with a US version to get a digital MPH display.

I would leave the gauges alone otherwise. Cool car.

Thank you. Two votes for "leave it alone".

Good tip on the OBC, @L39E (and great username btw) -- I'll check that when the car is back in my possession. May also look into swapping in a custom gauge cover.

I’m assuming it’s this car?

if so changing the odometer is not going to devalue the car IMO. I would also fix the askewed speedometer. It has had some mods already and the true collector cars are pretty unmodified clean examples. That being said I think your mods were tastefully done. Enjoy the car and drive it!

fitzpatrick

Yes, that's the car @jp884 . Agree that keeping mods tasteful likely won't affect value.

Speedometer angle can be adjusted, but the Mizwa sticker will stay : )

Keep your mind sharp. Keep KPH. Take KPH value, divide by 2, add back 10%. I've been doing it off our KPH signs for decades.

jac911

Another method of conversion is to multiply by 6. So 100 KPH x 6 = 600 or 60 MPH. Multiplying by .6 is most accurate, but my brain isn't mathematically adept so I use the 6 and use common sense with the result.

Keep as is. Don’t add doubt where it’s not needed.
