My choice would be 182 with Cup Packs. Full fat. Plenty of fun. Try and get the better seats though mine are horrible on a long journey and are the same IIRC as the proper cups and some standard 182's etc.
Fine if looked after and make sure cambelt is done properly as can't be done without tools. Can't stress this enough, anyone that says they've done one either hasn't or has knocked it out a tad, they will run and sometimes seemingly fine but down on power.
