Another vote for the mk1mr2 on your budget. Midship fun and plenty of support.
/edit. These require petrol and if you forget you wallet and drive too far, you do end up on the hard shoulder of the a19 waiting for the wife to come along with the petrol can of rescue. Not that that is where I am posting from now of course...
Ooops hehe!!
Another vote for Mk1 MR2 here. Lots of fun, easy to fix, cheap to pick up a driveable one.
