FJ is a good place to end up but if you want to learn your craft in something less vulnerable then something like MGB/Turner/TR4 in Guards means you can share costs with another driver (or sympathetic prepper
) and learn quicker to boot. If single seaters are your goal then the more time spent in a kart the better. Rock hard slicks on a corporate kart are as close to Dunlop historics as you will find!
