So after probably 4-6 months of looking at Mx5s I ended up buying this one.
It’s on 67k and fsh.
Had been undersealed before so fingers crossed for rust, sills looked okay, some rust right on the very edge where the spot welds are but no bubbling underneath.
Chassis rails were covered in underseal, peeled some away and the rails looked okay, no bits falling off when I poked around
Nice surprise was it has Meister R Zeta suspension all round and copes well with road humps.
