Janell - I'm gonna go against the flow here (usually do) but unless I'm doing serious modifications to a car, I've found the stock stuff works fine for an everyday driver....as you start to modify things, other things start going out of whack & oon its no longer a daily...if you just want to enjoy her whenever, don't waste your time trying all the shiny, fancy aftermarket stuff - just keep her in good repair
The cars I drive are all stock (except for my '79 Pageant Blue car) & they're all fun...here are the ones in my collection that I normally drive:
1979 Vermillion Red MGB
1974-1/2 Blaze MGB GT
1967 Red MGB GT
1963 Red Midget
1974 Red Midget
&, occassionally, 1963 MG1100
