What alternatives should I consider to a used Fiat 124 Spider sports?
The obvious alternative would be the Mazda MX-5. It can be had in a number of engine options, including an economical 1.5-litre petrol and a faster 2.0-litre unit with 158bhp, and you can get it with a folding metal roof. The MX-5 is a touch sharper to drive and its non-turbocharged engines are free from the lag that the Fiat's unit sometimes suffers from.
If you are looking for a more performance-oriented convertible, then a BMW Z4 is worthy of consideration. Not only is it plusher inside and comes with a refined folding metal hard top, its six-cylinder petrol engines sound fantastic and are much more powerful than even the Abarth version of the 124. It is much more costly to run, though.
