Pointless topic is pointless.

Sorry but standard 306 > standard mx5.

Handling-wise, that is.

Dump another £1,000 in the Mazda and that would be dramatically reversed.

Unfortunately as standard an MX5 is much, much more wobbly when compared to an old French can like a 306. We have a roof for a start. The MX5 needs strengthening, at least with a front strut-brace and a rear strut brace (or half-cage). Otherwise it flexes. Also, at present you can't take much advantage of the RWD, as yours is very, very unlikely to have an LSD. This means that it will just spin one wheel up and whilst you can have fun on wet roundabouts by lifting and going to fast, you can do that in a 306 just as easily!

Finally, standard suspension. The MX5 looks sporty, but the bread and butter models (ie the non-ltd editions) rocking stock setups are built for comfort, not sportiness - the target audience is people who are 40+ who want a weekend car with a drop-top.

Seriously, you have a good base car, but it's missing a lot of ingredients yet. If it were a cookie, you just have the baking tray on which to cook it right now.
