I've had one for a year and a half. Its a Mk3 2.0 Sport. I toyed with an earlier one, as I like the look of the mk2, but reading about chassis leg rust etc put me off. I love mine its the best 5.3 K I've ever spent. It took a lot of finding as I had a wide budget and looked at cars up to 12K. This one was the best as its been cherished, and low mileage. I've fitted RX8 yellow dot anti roll bars, which made a huge difference to the handling. I've also had the alloys refurbished in smoked chrome, fitted better tyres, as these cars hate sh1te tyres, got the alignment done. The 2.0 litre engine has loads of low down torque, and works really well with the 6 speed box, which is has very close ratios. Once you get used to it, it handles really, really well, and is the best B road car I've ever owned. Always puts a smile on my face when I drive it.
People may mock them, they've obviously never drove one. I toyed with the idea of a Honda S2000, price, availibilty compared to the 5 put me off. The 2.0 litre is plenty fast enough for B raods, the A roads are just a waste of time round here with traffic, so its the ideal motor. There's lots of choice when it comes to the Mk3, that's personally why I'd buy one, they are safer too. They rust, but not as bad as the earlier cars, I looked at some with loads of surface rust underneath, this was an 06 and an 08. The underbody rust protection is poor on Mazda's. Mine has hardly seen rain so there was no rust at all. I still rust proofed it though, the most horrible job I've ever done. Just take your time, walk away from any sh1tters, I looked at eight, a mixture of MK3's and MK3.5's. just take your time and look for a cherished one, they do exist at all ages. Problem is they are pretty cheap to buy, and run, so a lot are not looked after, I saw loads with tatty body work, scuffs, scratches.
I had a look at an Mk4 RF in the showroom, they look way better with the roof down, I actually prefer the look of the soft top MK4. I can understand why people would prefer the look of the 124 spider, once you get used to it, I think its pretty. The Mk4 MX5 looks like a BMW or something to me, which I personally don't care for, sure it looks more modern, but lacks the charm of the earlier cars to my eyes, which remind me of a Lotus Elan, Triumph Spitfire etc, not a BMW. Everybody to their own though. The MK4 was ok, but certainly not worth 6 x value of my MK3, stuff that...
