I'll limit my response to cars I have owned:

1958 TR3A. Engine bored out from 121.5cid to 150cid and SU carbs replaced with Weber sidedrafts. Suspension upgrades. Wild feeling with your elbows almost touching the asphalt with those low cut doors. A classic English sportscar I thoroughly enjoyed back in the day.

2003 Honda S2000 AP1. 9k rpm V-Tec engine with several tweaks increasing hp slightly over 10. Added a beefier front anti-sway bar and tweaked the 4-wheel alignment to Honda UK racing specs which combined to mitigate "snap" oversteer. It is what a small two seater convertible is all about. Still have an enjoy this one.
