But another and do both!
I've sort have tried to get both mine to be somewhere in between. The 968 is the daily but on KWs and poly bushes it is more than entertaining on quieter roads. I haven't had it on a track and I haven't striped any weight out of it or given up any comforts, so it's more a road car for occasional track use. The 944 turbo is going more the other way. I've striped all the sound deadening out, putting a cage in, bucket seats, air con removed etc. but I am going to put some carpets back in, so the intention is that's going to be a track car I can do the odd trip to Wales, Yorkshire or Scotland in.
It's up to you to decide how far you want to go with you're own car and what you can and can't live without using it on the road, but there's no reason why you can't make some mods that don't really effect the cars road manors but make it much better on a track. If you're not going to race it I don't see why you would want to go mad, even just making sure the brakes and suspension are in top condition and leaving it in standard form the 944 is very entertaining on a track.
