Do not adjust your contact lenses. What you see here is indeed a
Mk1 Mazda MX-5 with a BMW Z3 nose
Normally, If you're going to turn your budget sportster into a replica of something, the normal thing to do is to pretend it's something exotic. This is the dubious reason why MR2s and Pontiac Fieros get turned into Ferrari 355s, 360s and 430s, and why a chap in the Us has turned his 90s Mercury Cougar into a Bugatti.
For reasons we simply cannot fathom, however, this chap has turned his MX-5 (or Miata, in American-speak) into a rough approximation of a Z3. Except that the interior and, as far as we can tell, the rear half, remain determinedly Mazda.
It's all a bit odd, really. Especially when you consider that, over here in Blighty, a decent Mk1 MX-5 will set you back £1500-£2000, while the cheaper end of BMW Z3 ownership can be achieved for about the same price.
Maybe the chap just wanted the looks of a Z3 but (probably rightly) assumed that the little Mazda would be a more enjoyable steer.
So how much does our chap want for his Z3-X5? Well, last time we looked there was a bid up for $4200 (£2600), but it hadn't reached the reserve.
Perhaps he should be more creative with his advert: "1995 Miata with a BMW Z3 kit installed, painted Viper Red Metalic. includes hardtop . Runs great" is hardly the most detailed of descriptions...
