What with Rich's thread on reliable daily classics and Randy's thread on 'would you drive your first car now', coupled with the good weather, I've been pondering what the most reliable, cost effective and with some style open top sports car would be?

The obvious choice would seem to be a S1 Mazda MX-5 but I wondered if any of the old faithful British sports cars could be considered reliable; for example, MGBs are always priced well but are they a nightmare to own (DaveW?)?

Any thoughts of the cheapest, reliable, way to drive around with the roof down in style over the summer is?
