lookin for a MG

I'm in the market for an english sports car that's not too expensive and i was thinking of gettin a MG. Specifically I'm looking for probably a convertable that's high performance but also a nice looking and just all around a cool car. Now I know that a MG isn't exactly "high performance" , but i mean for a MG..... like one of the faster models, definitly with a 6 cyl if possible. If anybody could suggest which model MG to look for and where a good place to look for it would be, that'd be great... thanks for any info.
