Our 2003 MX5 had an annoying constant rattle coming from under the left seat - only when empty.
Had to take seat out and found source to be the little U shaped support the front on the seat slider adjustment rod passes through. Crimping the U a little tighter to hold the rod firmer did the trick!

I was aware that the 2003 MX5 we bought recently was a model that was prone to clutch judder. Our one doesn't seem too bad here though and we are able to get nice smooth starts just by using a few more revs than normal.

On our 2003 NB, the rear cup holder (not the CD storage box) lid is floppy which is annoying as it is right where your left elbow rests whilst driving. I can see a little spring on the left side has come loose or broken. What is the easiest way to get access to this and fix it? Thks.

Th...

Does anyone know the best DIY manual for a 2003 1.8 NB, and where to get it. Haynes looks like they only do a repair manual for earlier NA model. Also what is the best oil to use? Has anyone used Amsoil? On their US website there is a "Build List" where everything from oil filters, spark plugs and w...

OK, thanks guys for that. I'll get stuck into it...

Hi all, Wifey and I just bought our first MX5 today - a 2003 NZ 1.8 NB in Blue Mica. Looks and drives great! Now we can see what all the fuss was about over these last 21 years! Just 4 easy questions for y'all: 1. Fuel cap says 95 octane unleaded. Would it go OK on 91 or is that false economy? BP ha...
