Newbie - seeking advice

it's got a clutch - so she doesn;t need a bunch of power to have "fun"...lol. If it was me I'd just make sure the brakes and suspension are mechanically sound, upgrade the ignition, and add a single exhaust pipe and muffler. I don;t think I'd go further until she's got some seat time with it and keeps the tickets off her record. Just me - but I was a teenager and know what I did. If the car was more capable - I pushed it to it's limits. Best keeping it a wallowing, underpowered, brake fading mess until she get's some seat time.
